In the THC show, THC is short for Tanner Hall Connection. It documents Tanners rise back from the injury hell to the sport we all love seeing him in, skiing.
THC is also short for Tetrahydrocannabinol, which I guess pretty much everyone on this site is familiar with. THC is the main psychoactive substance in cannabis, weed if you like.
What I wonder, did it ever cross their mind? Did they do it on purpose? Its not like they try to hide their love for a little bit of ganj.
