Adds Anti-Weed (#92043)

## About The Pull Request

Adds Anti-Cannabis, or "Anti-Weed", a mutation of Cannabis which
contains Naloxone, Antihol, and Diphen-Synaptizine

These three chemicals will purge like 90% of all addictive substances
and their side effects (at the cost of negative mood and some tox
damage)

## Why It's Good For The Game

I thought it'd be really funny if a botanist offers you a smoke, you get
super high, and then to help they offer you another smoke
