The headline's question should really be reframed to question the validity of these restrictions in the first place.
I'm not a user of any of these sorts of substances, nor condone them, but there's zero reason for a free country to police personal use of such things. Sure, driving under the influence should be policed as a safety hazard, showing up to work out of your gourd should still get you fired, etc.
But there's little mandate that the government should be policing and prosecuting adults for potentially self-destructive private behaviors. Especially in light of all the other addictive and potentially self-destructive legal activities people are heavily involved in, any pretense of that mandate crumbles. Only when it threatens the safety, or disrupts the public civility, of other non-involved people should there even be a thought of government intervention. Any other conception to reduce individual drug use should be positive pressure like awareness programs and rehab centers.
