Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:00,640 --> 00:00:02,160
All around the world,
2
00:00:02,160 --> 00:00:06,000
marijuana is being decriminalized, or even made legal.
3
00:00:06,000 --> 00:00:08,680
But is this really a good idea?
4
00:00:08,680 --> 00:00:10,000
In the online debate,
5
00:00:10,000 --> 00:00:12,120
the harmful sides are often downplayed.
6
00:00:12,220 --> 00:00:15,200
So let's look at the three most powerful arguments
7
00:00:15,200 --> 00:00:16,620
against legalizing marijuana.
8
00:00:17,780 --> 00:00:24,560
[Intro - Kurzgesagt]
9
00:00:25,260 --> 00:00:26,460
Argument number 1:
10
00:00:27,300 --> 00:00:28,580
In the last few decades,
11
00:00:28,580 --> 00:00:31,460
marijuana has been engineered
to become much more potent.
12
00:00:32,080 --> 00:00:34,620
Today, marijuana is so potent,
13
00:00:34,620 --> 00:00:37,780
that it's actually a strong drug
that may cause psychosis.
14
00:00:37,780 --> 00:00:41,440
The main active ingredient of marijuana is THC,
15
00:00:41,440 --> 00:00:45,420
and there's strong evidence
that THC is related to psychosis
16
00:00:45,420 --> 00:00:47,580
regardless of other risk factors.
17
00:00:48,100 --> 00:00:51,140
Marijuana also contains a substance called CBD,
18
00:00:51,140 --> 00:00:52,829
that seems to counteract its effect.
19
00:00:53,400 --> 00:00:57,980
It's even being tested as a treatment
against psychosis and anxiety.
20
00:00:58,320 --> 00:01:00,374
But because it doesn't make you high,
21
00:01:00,374 --> 00:01:03,400
growers have gradually decreased the amount of CBD
22
00:01:03,400 --> 00:01:05,500
in marijuana over the last few decades,
23
00:01:05,500 --> 00:01:07,860
while increasing THC levels.
24
00:01:08,640 --> 00:01:16,180
Sample testing showed that THC levels have risen from around 4% in the 1990s to nearly 12% in 2014,
25
00:01:13,940 --> 00:01:16,320
to nearly 12% in 2014,
26
00:01:16,320 --> 00:01:21,440
shifting the ratio of THC to CBD
from 1:14 in 1995
27
00:01:21,440 --> 00:01:24,540
to about 1:80 in 2014.
28
00:01:24,920 --> 00:01:28,240
It's unclear how precise those tests were, however.
29
00:01:28,780 --> 00:01:32,820
Overall, recent findings suggest
that the more marijuana you consume,
30
00:01:32,820 --> 00:01:34,120
and the stronger it is,
31
00:01:34,120 --> 00:01:36,580
the higher your risk of developing psychosis.
32
00:01:37,280 --> 00:01:41,040
But how high is the risk of psychosis
for the general population?
33
00:01:41,420 --> 00:01:42,880
A study from Britain found that
34
00:01:42,880 --> 00:01:48,380
while marijuana use has risen significantly
between 1996 and 2005,
35
00:01:48,380 --> 00:01:50,360
the number of schizophrenia cases โ
36
00:01:50,360 --> 00:01:52,960
a type of psychosis โ remain stable.
37
00:01:53,380 --> 00:01:56,200
The risk of marijuana induced psychosis
38
00:01:56,200 --> 00:01:57,860
remains the highest for people
39
00:01:57,860 --> 00:02:00,940
who already have a high risk of psychosis to begin with.
40
00:02:01,780 --> 00:02:03,500
For them, it seems more likely that
41
00:02:03,500 --> 00:02:06,160
marijuana speeds up
the development of their condition,
42
00:02:06,160 --> 00:02:09,180
rather than causing it,
as far as we know right now.
43
00:02:09,780 --> 00:02:11,360
So the reasoning goes,
44
00:02:11,360 --> 00:02:13,760
if fewer people have access to marijuana,
45
00:02:13,760 --> 00:02:16,640
the lower the risk of marijuana-induced psychosis.
46
00:02:16,680 --> 00:02:18,600
But actually, you could argue that
47
00:02:18,600 --> 00:02:21,380
precisely because marijuana is illegal,
48
00:02:21,380 --> 00:02:23,940
more people will end up with psychosis.
49
00:02:24,660 --> 00:02:27,700
Prohibition makes illegal drug stronger and more potent,
50
00:02:27,700 --> 00:02:31,180
because this way you can ship
more product in a smaller space
51
00:02:31,180 --> 00:02:33,280
and sell it at a greater profit.
52
00:02:33,440 --> 00:02:36,760
This is what happened during
the prohibition of alcohol in the US,
53
00:02:36,760 --> 00:02:38,960
where hard liquor became the norm.
54
00:02:39,420 --> 00:02:41,920
And the same is happening with marijuana now.
55
00:02:42,380 --> 00:02:46,240
Imagine a world where liquor
is the only alcohol available.
56
00:02:46,240 --> 00:02:48,880
You have the choice of either not drinking at all,
57
00:02:48,880 --> 00:02:51,220
or getting much drunker than you would like to.
58
00:02:51,420 --> 00:02:54,920
This is the situation for many marijuana smokers today.
59
00:02:55,220 --> 00:02:58,040
People didn't stop drinking during prohibition,
60
00:02:58,040 --> 00:03:01,960
and the numbers show that laws
don't deter people from using marijuana.
61
00:03:02,000 --> 00:03:04,420
We can't make marijuana go away,
62
00:03:04,420 --> 00:03:06,380
but we can make it safer.
63
00:03:06,820 --> 00:03:08,300
If marijuana were legal,
64
00:03:08,300 --> 00:03:10,760
there would be more options for consumers,
65
00:03:10,760 --> 00:03:15,140
and regulators could, for example,
insist on a high level of CBD.
66
00:03:15,320 --> 00:03:19,160
Just like most people don't drink
an after-work bottle of vodka,
67
00:03:19,160 --> 00:03:23,880
many people would gladly consume
the after-work beer version of marijuana.
68
00:03:24,680 --> 00:03:28,020
Argument 2:
Marijuana is a gateway drug.
69
00:03:28,020 --> 00:03:29,240
If it's legalized,
70
00:03:29,240 --> 00:03:33,240
there will be a spike in the use
of much more dangerous drugs.
71
00:03:34,140 --> 00:03:35,920
A 2015 study found that
72
00:03:35,920 --> 00:03:38,980
about 45% of lifelong marijuana users
73
00:03:38,980 --> 00:03:41,660
took some other illegal drug at some point.
74
00:03:42,340 --> 00:03:45,320
Legalizing marijuana could reinforce this trend:
75
00:03:45,320 --> 00:03:47,940
As more young people try legal marijuana,
76
00:03:47,940 --> 00:03:50,060
they might end up trying harder drugs.
77
00:03:50,700 --> 00:03:55,180
But it turns out that the real gateway
to drug use comes much earlier:
78
00:03:55,180 --> 00:03:56,280
Cigarettes.
79
00:03:56,600 --> 00:03:58,040
One study showed that
80
00:03:58,040 --> 00:04:00,820
teens who started smoking before the age of 15
81
00:04:00,820 --> 00:04:05,000
were 80% more likely to use illegal drugs
than those who didn't.
82
00:04:05,000 --> 00:04:10,400
And a 2007 study found that teenagers
between 12 and 17 who smoked
83
00:04:10,400 --> 00:04:13,100
were three times more likely to binge drink,
84
00:04:13,100 --> 00:04:16,880
seven times more likely to have used
drugs like heroin or cocaine,
85
00:04:16,880 --> 00:04:20,900
and were also seven times more likely
to resort to marijuana.
86
00:04:21,540 --> 00:04:23,200
But if that's the case,
87
00:04:23,200 --> 00:04:27,640
how could making more drugs legal
stop the use of hard drugs?
88
00:04:27,900 --> 00:04:30,300
At first, it's important to acknowledge that
89
00:04:30,300 --> 00:04:32,840
people don't use drugs because they're legal or not.
90
00:04:33,200 --> 00:04:35,000
If you want to buy any drug,
91
00:04:35,000 --> 00:04:37,060
you'll always find someone happy to sell.
92
00:04:37,400 --> 00:04:40,280
The real question is why do people develop
93
00:04:40,280 --> 00:04:42,920
an unhealthy relationship with drugs at all?
94
00:04:43,460 --> 00:04:45,380
Studies show that certain conditions
95
00:04:45,380 --> 00:04:49,020
make people especially vulnerable
to drugs and addiction.
96
00:04:49,020 --> 00:04:50,660
A difficult childhood,
97
00:04:50,660 --> 00:04:51,760
early trauma,
98
00:04:51,760 --> 00:04:53,600
low social status,
99
00:04:53,600 --> 00:04:56,040
depression, even genetic factors.
100
00:04:56,460 --> 00:05:01,180
Which drug they get addicted to
is more often than not a matter of chance.
101
00:05:02,520 --> 00:05:05,500
Addicts take drugs to escape their problems.
102
00:05:05,500 --> 00:05:08,040
But drugs don't solve any of those problems,
103
00:05:08,040 --> 00:05:09,940
and instead become a new problem.
104
00:05:10,260 --> 00:05:14,080
But punishing people
for their unhealthy coping mechanisms
105
00:05:14,080 --> 00:05:17,320
doesn't change anything about
the underlying causes either.
106
00:05:17,420 --> 00:05:21,500
So some argue we need to
take a completely different route.
107
00:05:21,780 --> 00:05:23,240
In 2001,
108
00:05:23,240 --> 00:05:26,120
Portugal had one of the worst drug problems in Europe.
109
00:05:26,120 --> 00:05:29,260
So it was desperate enough to try something radical:
110
00:05:29,780 --> 00:05:33,580
Possession and use of
all illegal drugs was decriminalized.
111
00:05:33,940 --> 00:05:35,620
You would no longer be arrested;
112
00:05:35,620 --> 00:05:39,040
instead, authorities launched a major health campaign.
113
00:05:39,440 --> 00:05:41,580
People who were found with a small amount
114
00:05:41,580 --> 00:05:43,460
were referred to support services,
115
00:05:43,460 --> 00:05:45,620
and got help with treatment and harm reduction.
116
00:05:45,960 --> 00:05:49,680
Drug use was seen as a chronic disease, not a crime.
117
00:05:50,100 --> 00:05:52,180
The results were stunning:
118
00:05:52,180 --> 00:05:55,380
the number of people
who tried drugs and kept using them
119
00:05:55,380 --> 00:05:59,080
fell from 44% to 28% by 2012.
120
00:05:59,660 --> 00:06:01,980
The use of hard drugs decreased,
121
00:06:01,980 --> 00:06:05,740
as well as HIV & hepatitis infections
and overdoses.
122
00:06:06,260 --> 00:06:11,840
Making drugs legal might overall
help society much more than it harms it.
123
00:06:13,020 --> 00:06:15,000
Argument number 3:
124
00:06:15,000 --> 00:06:17,740
Marijuana is addictive and unhealthy.
125
00:06:17,740 --> 00:06:21,320
It needs to remain illegal
to keep harm at a minimum.
126
00:06:21,960 --> 00:06:25,720
While marijuana addiction is
more psychological than physical,
127
00:06:25,720 --> 00:06:27,320
it is still a real problem.
128
00:06:27,500 --> 00:06:30,420
The demand for treatment
for marijuana addiction
129
00:06:30,420 --> 00:06:33,120
has more than doubled in the past decade alone.
130
00:06:33,460 --> 00:06:38,280
In total, about 10% of people
who try marijuana will become addicted.
131
00:06:38,400 --> 00:06:41,560
This is also related to higher THC levels.
132
00:06:41,940 --> 00:06:43,940
A study released in 2017
133
00:06:43,940 --> 00:06:46,760
tracked the potency of marijuana
in Dutch coffee shops
134
00:06:46,760 --> 00:06:48,700
over a period of 16 years.
135
00:06:49,240 --> 00:06:52,300
For every 1% increase in THC,
136
00:06:52,300 --> 00:06:55,360
60 more people enter treatment nationwide.
137
00:06:55,680 --> 00:06:57,460
In terms of negative health effects,
138
00:06:57,470 --> 00:07:01,860
some studies linked marijuana use to
increased blood pressure and lung problems,
139
00:07:01,860 --> 00:07:05,940
while a 2016 study found that
marijuana use was unrelated to
140
00:07:06,000 --> 00:07:10,020
physical health problems,
except for a higher risk of gum disease.
141
00:07:10,260 --> 00:07:14,260
Some studies showed that
marijuana use alters teenagers brains,
142
00:07:14,260 --> 00:07:16,060
and decreases their intelligence;
143
00:07:16,060 --> 00:07:19,740
but when more recent studies
took drinking and smoking into account,
144
00:07:19,740 --> 00:07:21,960
the results were inconclusive.
145
00:07:23,160 --> 00:07:24,700
Overall, research shows that
146
00:07:24,700 --> 00:07:28,620
taking any drugs while the brain
is still in development is bad for you.
147
00:07:29,600 --> 00:07:34,060
But the truth is, we don't know yet
how unhealthy marijuana is.
148
00:07:34,060 --> 00:07:35,840
We need more funding for research,
149
00:07:35,840 --> 00:07:38,680
which is hard to get while marijuana remains illegal.
150
00:07:39,120 --> 00:07:41,600
We can put what we know into perspective though.
151
00:07:42,140 --> 00:07:46,000
16% of people who consume alcohol
become alcoholics,
152
00:07:46,000 --> 00:07:49,660
and 32% of people who try cigarettes
become smokers.
153
00:07:50,100 --> 00:07:53,000
We know for sure alcohol affects your brain,
154
00:07:53,000 --> 00:07:55,420
destroys your liver and causes cancer;
155
00:07:55,420 --> 00:07:57,380
while tobacco clogs your arteries,
156
00:07:57,380 --> 00:08:00,420
destroys your lungs and also causes cancer.
157
00:08:01,320 --> 00:08:04,500
3.3 million people die from alcohol abuse each year,
158
00:08:04,500 --> 00:08:07,480
while smoking kills more than 6 million people.
159
00:08:07,860 --> 00:08:12,900
Nobody is suggesting tobacco and alcohol
are harmless just because they're legal.
160
00:08:12,900 --> 00:08:18,640
Also, nobody is seriously proposing to prohibit them even though they are extremely dangerous.
161
00:08:19,040 --> 00:08:22,740
Legality is a way to exercise some control over them,
162
00:08:22,740 --> 00:08:25,400
especially when it comes to protecting young people.
163
00:08:25,720 --> 00:08:30,920
It's often much harder to buy legal drugs
for teenagers than to buy illegal ones.
164
00:08:31,080 --> 00:08:33,120
Official sellers can get hefty fines
165
00:08:33,120 --> 00:08:36,380
and lose their license if they sell to underage kids.
166
00:08:37,020 --> 00:08:41,980
Legality creates incentives here
that drug dealers can't exploit.
167
00:08:44,000 --> 00:08:47,480
So making marijuana legal doesn't mean endorsing it.
168
00:08:47,480 --> 00:08:50,920
It means taking responsibility for the risks it poses.
169
00:08:51,100 --> 00:08:54,480
It could also open the floodgates
to tons of new research
170
00:08:54,480 --> 00:08:57,960
that shows us how harmful
it really is, and to whom.
171
00:08:59,540 --> 00:09:01,320
Conclusion:
172
00:09:01,510 --> 00:09:03,000
Marijuana is a drug,
173
00:09:03,000 --> 00:09:06,000
and just like any other drug,
It has negative consequences
174
00:09:06,000 --> 00:09:08,940
for a sizable portion of the people who use it.
175
