Either grow skunk, its a great hobby, looking after your plants, flowering them, drying them and curing them is a fantastic feeling, and one of the most rewarding things i do. Salvia is a legal alternative, but its nothing like weed. Its makes you trip (Hallucinate sp?)

If you buy some, make sure your getting 15x or 20x extreact, as the leaf doesnt do much.

Other herbs apart from the sacred skunk are all crap.
