You need to do some research on thujone
before you go making ridiculous statements.
Except from link below:
"The toxicity of thujone in the brain is believed to result from its structural similarity to tetrahydrocannibinol, or THC (3) , the active compound in marijuana. ...Thujone and THC have similar shapes, and it is believed that they interact with the same biological receptor to produce their similar psychological effects"

So, in your opinion, the active ingredient in cannabis is really thujone? Otherwise I'm not entirely sure what point you're trying to prove.
