i kinda disagree, you shouldnt be growing any plant you want: mostly invasives and poisonous ones, alot of ornamental are poisonous. plus the one reason that nobody mentions, is poaching wild plants, this will only encourage poaching of wild plants. with succulents this has happened with alot of species especially for echeveria, dudleyas(native to various california ecosystems, South of the united states, and mexico area. i believe korea has a craze for these plants is pretty much encouraging the type of poaching, horticulture cant supply enough , or cultivate wild ones due to niche environments for some species. Rx drugs, should be monitored by doctors to avoid complications, you dont want to take immuosuppreseants/ or heart disease drugs just because you were slightly under the weather that day. i think hard drugs should be de-criminilized.
