My wife has recently been prescribed cannabis by her doctor. As she's never been a smoker she's finding inhalation difficult. She also has concerns about potentially harmful smoke by products. To help her I'm on the hunt for the most effective, efficient and safe delivery system. I've done some reading on vaporizers and think this could be a good way to go. I'd like to ask my fellow forum members who have current or previous experience with this type of apparatus to give me their frank recommendations. Which one they have found to be the most effective and easiest to operate. Also is their another method we should consider? Unfortunately ingest-able forms are not an option. Any constructive input is much appreciated.
