I like growing things. So many things on that list I need to plant. I've already grown some of them.
I need to get a new salvia plant, before it is made illegal.
There are some in that list I'd like to try.
I'll give my opinion of those I have used:
HBWR/LSAs - These have produced the most beautiful, meaningful, and helpful trips of my life. The side effects can be hard to tolerate, but it is definitely worth it if you can get past the physical suffering. I've grown these. They are easy to grow, but must be protected from cold. They do not flower until the second year. Morning glories would be better for non tropical environments. I've grown them too, and they are about the easiest thing to grow.
Cacti/mescaline - Mescaline is a really nice substance. It hasn't produced any +4 type trips for me, but it is fun and has given some meaningful and memorable experiences.
Salvia - Very intense and weird. I like it, but have not yet "broken through". It can be hard to grow. I've done it before, and my plants died. I'll try again.
Kratom - Very much like poppies, but more expensive. I'd like to try growing myself. Definitely worthwhile if you like opiates.
Desmanthus - Easy to grow outdoors, supposed to have pretty high DMT content. I've got some growing, but haven't used any yet.
Calamus - I haven't grown it, but I have had the misfortune of eating it. Not fun unless you like hours of puking, cramping, and puking some more with little or no psychoactive effects.
Kanna - I'd like to grow this. I've smoked it with good effects. It doesn't give a strong high, but there is a nice mood lift. Maybe I could get higher if I smoked more, but I am all out. It may be useful as an antidepressant. I'm going to buy a cutting and give it a try.
Sinicuichi - Never tried growing it. It is ok as an intoxicant in small or moderate amounts, but not very strong or psychedelic. Large amounts can cause the most painful muscle cramps you can imagine, all through the body.
Kava - This is pretty nice as a relaxant, sedative, and mildly euphoric. I don't know how easy it is to grow, but I may look into that.
Voacanga - I've eaten the seeds at low dose to see if it would do anything. It did not. Others have had vomiting and cramping from larger amounts, with little or no psychoactive effects. Not worth it.
Ephedra - Ok as a stimulant and appetite suppressant in small-moderate amounts. It can really raise BP and heart rate if too much is used. It is also easy to grow, from what I've read. I may grow some.
Catnip - May have mild sedative effects, may have been placebo. The taste of catnip tea is nice, IMO, so I'll drink it again in the future. I tried to grow some, but the seeds never came up. It should grow and spread like a weed once established.
I'd like to try lagochilus inebrians, coleus, and wild dagga. I'd try growing khat if I can get some seeds. And Iboga. I've been wanting to try ibogaine for a long time.
