Legal buds contain no THC and will not get you stoned. If you're expecting to get stoned like from the real thing, you will not. It is just an alternative to smoking and will not get you high in any way, despite what people think or say.

Salvia is a legal herb that does get high, but not like MJ. It lasts for only about 15-20min and some people have described the high being very intense and visual.
