Go see a doctor, if what you say is correct, he will give you a certificate, for immigration. I had 9 months of just that, I had a disc, herniate in my lower back. The orthopaedic surgeon, gave me ongoing certificates, until I could travel again.
were you always a sanctimonious individual? Or has it developed recently. As a cancer survivor, canabis contributed enormously in my rapid recovery. It eliminated the two worst post surgery effects. Nausea, and appetite loss. The guy who got 5 years ban, did heaps more than get caught with a joint, after 30 years residence, I have known enough expats, who were caught, none of whom ever faced any type of ban.
