Mushrooms is one of the easiest drugs to procure.

Some species like Psilocybe semilanceata grow in the wild, both in Europe and North America. You can just pick them if you know the type of habbitats to look for.

You can buy grow kits semi-legally (grey area, might vary on where you live) and you don't need any extra equipment. You get a plastic box and you literally just add water.

If you want to save money, you can buy only the spores. Then you just need some substrate which you can buy either at garden supply store or at a supermarket. Biggest issue is ensuring sterility, so a pressure cooker is recommended, but there are ways around that.

I'd say it's easier to grow shrooms at home than it is to make alcohol. You don't need any specific equiment like a still for distilled drinks, and you don't need any trial and error like you do when making fermented drinks. I know you could make alcohol without any equipment, but the end result will probably be quite poor. Meanwhile the shrooms grown without any equipment will be the same as any.
