Ive seen them at a few houses in the suburb I live in (and damn they get very tall), San Pedro is very easy to find + get from the (I edited this bit out) stores, but I guess they could be under the same category as shrooms + poppies!? legal to grow but illegal to pick / use for drug consumption, could be wrong so dont quote me on that...
yup san pedro are legal to grow but not to ingest in NZ.i have a reputable source to obtain them from if u want ill private message you with them (they are at really good prices as well). they are from a nursery and are Trichocereus pachonoi crossed with Trichocereus scopulicola.
