Bassist looking to build vape into his rig

I suffer from some aggressive rheumatological disease which causes joint pain and inflammation. I've been managing my pain with cannabis for the last year. I play bass and vaporize with an mflb. I play for long periods of time with bands and when I practice, and find it inconvenient to have to stop playing to vape every 10 minutes (I keep a very light buzz to keep my head as clear as possible when playing)

I would like to build a vaporizer into my setup. I was thinking some form of foot switch...
