remove THC from the addict trait

[Mordent]

I'm of the opinion that "dude, I'm not addicted, I just need it to mellow out and get bitchy if I can't get any" is basically an addiction. Conversely, random people asking for weed consistently from botany is a given anyway, so it's not like it's hard to source. I'd be for removing it solely because it's not as debilitating as an addiction to some of the other addictive reagents.
