You may do so on your own private property. If you wish to use public roadways, you must abide by the laws set by your state, which must balance the costs to society of your choices against your ability to make them.

not at all.

Drug use has one victim : the user. Time and time again it has been shown that legalization and cure are far more efficient and cost less to society but still many countries cling to the idea that beating up somebody who is down will magically solve the problem.

What about the family of the user? What about friends and relatives affected by a user's addiction?

If you think the impact on a counterparty in a car accident should be taken into account, I would think family should be top-of-mind.

I mean why not make alcohol illegal because of the chance that it could negatively affect the people around you?

That has a much higher likelihood than my not-wearing-a-helmet affecting someone else but very few people would support alcohol prohibition.
