When you get a chance, investigate! You'll be amazed at how much has been kept from you until this point. You have an endocannabinoid system in your body and brain, specific receptors for THC and 100+ other cannabinoids found in plants, and made by your body. This system is responsible for the regulation of health. When it isn't properly supplemented, illness results, which is why cannabis treats so many conditions. It is literally part of us and has been for millions of years, in our diet and culture and medicine from before recorded history. All you have to do is wander away from the official narrative, which for 100 years has been "marijuana kills brain cells, causes cancer, and makes people violent or lazy".
The Nazi's were masters of propaganda. They said "if you're going to tell a lie, tell a BIG lie, and tell it often". The lie about cannabis is one of the biggest and it has been told nonstop for generations now.
