Wileniec has hereditary multiple exostoses, a condition that locates in his joints and pinches his nerves, causing a pain that he equates with stepping on a nail.
It's bad enough that it has disrupted his life and interrupted his education because of time off for surgeries. At age 21, he's two credits shy of graduating from Grade 12 at Nutana Collegiate.
Wileniec said he was able to use his vaporizer at school for two years with no problem. The principal and staff knew what he was doing and why.
But a week ago, he received a letter from the Saskatoon Public School Board: No more pot on school grounds, and no being at school while under the influence of medical pot – a decision he said is unfair.
"A diabetic [can] come to school, they're still able to come to school. Any other person that uses any other type of medicine are able to come to school," he said.
Wileniec said he's not intoxicated by the marijuana. It's all about pain management.
"After I take a hoot, the pain would go away and my mind would be diverted from concentrating on it," he said.
Wileniec is not sure of his options and his family is supportive.
"I don't think I'm high. I've dealt with my pain. When you're high, you're delusional."
The right medicine
Wileniec said he was diagnosed with his condition at age 17. He started smoking pot recreationally when he was 14 years old and got his medical marijuana prescription at 17.
He has tried conventional prescription drugs, from Tylenol 3 to morphine, but didn't like how they clouded his mind.
He also said that the terms of his current prescription are such that he has to smoke the marijuana, and he can't eat it.
The Saskatoon Public School Board has not responded to requests for comment.
