Answering to the OP directly, no it is not. None of it should be legal. Here's why in my own opinion;
I smoke and love it and its wonderful and I am 59 and no errors as of yet. I have never used drugs and do not drink, ever. Never developed a taste for it, as most males in our culture here in the USA love beer at least, though I cook with it with my myriad of Mexican recipes.
Down home in the Yucatan, tobacco is organic and I get it from there and have it shipped to me here in NM, and it is just cut and cured from the fields and then sold in bulk at the local vendor level, ASAP. It's cheap and delicious. Drugs there are a non issue. Beer is a mainstay there for cooking and is also organic. If you type in to find out any incidences of abuse for same, drugs, et al, there is little to none.
Drugs and alcohol abuse and obesity is an American problem per se.
Just some other input along with the American issue with same.
