Yep, you left out coca. I dn't advocate the use of any, but I do believe opium poppies, mj and mushrooms should be legal. Coca not so much, but that is a personal preference.
i do not recommend any of the above with the exception of buddah butter made from mj
also, i do not know what drugs can be synthesized or made at home (maybe lsd)
i also forgot datura, a plant that grows wild in ca, but may be purchased in nurseries...
