From the article:
Whatever
you think about marijuana legalization, it’s important to avoid making bad
arguments. There may be good reasons to legalize marijuana. But if there are,
the following arguments shouldn’t be considered to be among them.
1.
‘Marijuana Is Harmless’
This is perhaps the worst
argument in favor of legalization. It is a well-established fact that marijuana
use carries significant negative health effects, particularly to mental health.
For instance, a
2017 review of research by
the National Academies of Sciences, Engineering, and Medicine found that “there
is substantial evidence of a statistical association between cannabis use and
the development of schizophrenia or other psychoses, with the highest risk
among the most frequent users.”
Along those lines,
the authors of one study boldly concluded that “evidence
from epidemiologic studies provides strong enough evidence to warrant a public
health message that cannabis use can increase the risk of psychotic disorders.”
Other studies have found a strong link between marijuana use and
mood disorders and suicidal
ideation,
addiction,
altered brain activity,
decreased executive function,
damage to the brain
(particularly white matter), and negative effects on
learning, memory, and attention,
among other things. Need I say more?
The science is very clear:
marijuana is
not harmless. It is a
performance-degrading drug that can significantly damage one’s mental health.
“But
what about medical marijuana!?” Well, the term “medical marijuana” is
misleading because it is not actually the marijuana plant that has medicinal
properties, but cannabinoids (namely CBD and THC) found within the plant. Some
research shows these cannabinoids can help with pain management, nausea and
vomiting, and multiple sclerosis spasticity.
We shouldn’t oppose
research and development of cannabinoid-based prescription medicines, provided
they go through the same rigorous regulatory process by which other medicines
are approved. Indeed, several already exist: dronabinol, nabilone, and
epidiolex are all cannabinoid medicines at various stages of FDA approval.
While medical marijuana of this kind is unobjectionable and ought to be
supported, the raw marijuana plant is
not medicine.
We
also need to weigh the alleged benefits of marijuana against its negative
health effects. Given the strong scientific consensus in favor of adverse
health effects, is it really all worth it? And should we really start
legalizing marijuana before these effects are known in detail and among the
broader public?
