This can if you want include prescribed drugs, alcohol, tobacco, etc.

All of them.

Hmm. Normal stuff people do like caffeine or pain killers when you're hurt badly. Used to smoke cigs but quit in my 20s. I like to take b12 vitamins everyday. I'm prescribed adderall. Been taking that since I was kid. I have the attention span of a cat. I've smoked a lot of pot when I was teenager and did some coke (it's nothing special) for a short bit.

None really as I don't like to lose control over my mind.

I may be getting addicted to energy drinks but I'm not rally sure about that. Damn you Rockstar for creating "Killer Cherry", the only and best cherry soda.

Well since we can almost use anything to post here

Liquor, beer, wine coolers, wine, cigars, e-cigs, pipe tobacco, coca cola

If you mean the illegal, possibly insanity inducing and stabby kind, none.

If you mean regulated and doctor prescribed, Cymbalta (I think that's how you spell it), and the occasional decongestant.

Nothing illegal, I don't smoke either, nor do I drink. However, I am currently taking duloxetine, which was prescribed to me to help with anxiety.

Yeah, that's how you spell it, but Cymbalta is the brand name, the actual name of the drug is duloxetine, which is what I take.

Anti-depressants fall into that category too. 

Hmm, various forms of cannabis, xtc, speed, cocaine, caffeine pills, mushrooms, various types of alcohol. Fun times.
