CBC News recently did an article on cannabis yoga. They interviewed Trina Wannamaker who teaches cannabis yoga at Green Sprouts Café and Vapor Lounge in Barrie, Ontario as well as some of her students and the owners of the lounge.
 
Canadian Yoga Alliance was asked to comment on the practice. You can read the CBC article and Violet Pasztor’s response that “yoga itself is the high” here:
