My mum has stage 2 COPD and it has stopped her in her tracks.. we are very open to trying the oil, but don't know where to start. We live in BC Canada, I believe it is legal here, and I possibly know some avenues to get some. But where do I start, how much dosage, what kind.. I have read some of the posts here but seem way to advance for me, please if someone can help right from the start I would really appreciate it!!!
