It's like reading where corona virus started Japan, China and even the US, what one is believable? People have been driving under the influence of weed since the 50's that I know of. It depends on your tolerance level. My husband has been driving transport trucks for 36 years and has smoke weed longer than that on a daily basis. Yes, he smokes it while driving as long as he has driven a truck. He is not the only truck driver to smoke while driving as him and a group of over 20 stop and have sessions with each other. He knows more about weed than anyone I have ever met. He is also one of the most safest drivers I know. I do not believe anything I read online about the subject as most is written by people who have no clue about weed.
The weed I grow and turn into oil for medical use is purple kush. It has a very high level of thc (which is what cures) and it is an indica strain which makes you sleepy so you take it at night before you go to bed. While you sleep your body is healing.
Sativa strains are uplifting meaning it wakes you up, gives you energy. That is the kind people drive on.
I did a lot of studying before I did this. I read and watched videos on Rick Simpson (who cured over 5000 people) before I started to make his oil. I have given it to a handful of people who had positive results. JohnnyDos and I were pming back and forth about it because he smoked weed for years. If I had known he had cancer at the time I would of told him to go buy 2 pounds of it and make the oil to cure himself (it only takes 60 days to cure). When he died while were talking I was so shocked and it hit me hard. I will miss him for the rest of my life.
