Quit tobacco and still smoke cannabis?

I have had quite a few people talk to me over the recent months about wanting to stop tobacco smoking but still retain the ability to keep smoking cannabis.

Is this achievable? Can you both give up tobacco and use cannabis? Keeping watching till the end of the video for an interesting insight into this issue.



Sorry about the still frame above! I am a lot more friendly than that pictures suggests...if I could just find a way to use a different frame.

Any comments on this video are very welcome whether as a therapist or as a user.
