Question : Hello Dr. I smoke marijuana often and regularly. Recently I have noticed that smoking gives me palpitations which keep me awake at night. I asked my GP for a prescription of beta-blockers, but did not tell him I would be smoking marijuana whilst taking them. I realise marijuana is not healthy, but is there any sort of interaction between the two I should be wary of? Thank you, XXXXXX
Oh - I should mention I also take Fluoxetine daily.
