You say that as if people don't have the option not to purchase illegal drugs. If an individual can't be bothered to settle on a legal alternative, that's a roll of the dice they'll have to take. The conventional wisdom is that fewer people will do drugs if they're illegal. I'm not certain I wish to know if it's true or not. I accept the finding among some that use will rise if drugs are legalized.
You don't know what you're talking about. You really think that it's better for people to drink than smoke weed? Have you ever done either? (spoiler alert: drinking gets you
much more intoxicated then weed) You seriously believe all the aforementioned social costs are worth it for some percentage of people to not do drugs?
Is this really how you think?
