I had smoked marijuana and cigarettes for 24 years. I have been practicing Qigong since mid Aug 2004 trying to combat addiction, depression, peri menopause symptoms,and 6 year OCD problem. I am happy to say I quit marijuana completely. The cigaretes are on their way out the door!! . I am down to 5-10 a day average. I am sure I am almost over my addictions. I feel much younger and my spirit is lighter when I do the exercises. I have to more pain from menses either.
