In truth, you should refrain from Smoking marijuana or anything else before surgery. Any medic will tell you that. I used to smoke cigarettes, then switched to vaping to quit cigarettes. I smoked because there was no vaping yet. I believe this statement is partially true because vaping is much safer for health than cigarettes. I recently noticed that my sister is interested in what I'm vaping. I decided to direct her immediately so that she would first watch the video about best starter vape. If she wanted to start vaping, she will know how to do it properly. As an older brother, I did better for my sister.
