Many people use cannabis to help them fall asleep. For some, it becomes the only way they can drift into the netherworld. For the longest time, I suffered from this condition as well, laying awake staring at the roof, counting the minutes go by. Cannabis helped me tremendously during the hardest parts of my insomnia ridden years, but it was not the only thing that helped me eventually get to a point where I could pass out without the need of any substance.
