I don't agree.Weed is far less addictive and dangerous than alcohol or cigarettes.
Alcohol-related deaths are the third leading cause of preventable deaths in the US.
Smoking is number one.
High blood pressure (obesity) is number two.
And yet we don't criminalize that kind of self-harm. Nor do we refuse spending gobs of money treating them.
There are too many REALLY strong variants out there that pushes some pot into damn near hallucinogenic.
There are pot strains that make it impossible to drive a car for instance. As proven by videos. Once a person gets to the 40 Nanograms mark... they start royally fucking up on driving test. Even ones who smoke pot everyday.
Mostly, when it comes to driving, alcohol is more impaired than pot. No argument. But today's purer strains are pushing the envelope.
