I do most of the time (I tend to speed), but I don't like having to follow the law . I was diagnosed with juvenile arthritis at 12, and started toking at 14, and it completely relieved my pain. I won't do it now because I have children and am terrified that the government would take them away, and the Vicodin the doctor prescribed made me unable to function. Pleasant, but doesn't work when I need to take care of people. It cuts the time I can spend in my career pursuits quite a bit, and is generally uncomfortable.
I obey the law only because they hold what is most dear to me over my head.
