That's soapbar. It may be cheaper but it's poison. You can smoke it if you want but i'd say it's more important to have your health than a cheap buzz.

What you should do is take it back where you got it and tell the guy it's shit and that you want your money back.

This is what's in it;

Beeswax, turpentine, milk powder, ketamine, boot polish, henna, pine resin, aspirin, animal turds, ground coffee, barbiturates, glues and dyes plus carcinogenic solvents such as Toluene and Benzene
