She remembered it was April 20, or "4/20," and mourned over not being able to celebrate with her friends on Parliament Hill. To mollify her disappointment, and to satisfy my curiosity, I said we'd drive past. I gaped as we passed hundreds of teens and adults lounging on the sunny grass by the capital's green-roofed buildings. Navy blue police figures dotted the crowd, but everyone looked peaceful and relaxed, chatting in groups and walking across the lawn. I squinted and couldn't see anyone smoking, but I knew in whose honour the party was being thrown. It was for Mary Jane. Who is this Mary Jane, you ask? Her green face adorns the alternative Canadian flag. She hovered over our fathers' long-haired plaid-shirted days. Illegal but sometimes turned a blind eye by police, Mary Jane drifts through the streets of Halifax, wafting down from windows, sneaking out of alleyways and crashing on squishy second-hand couches in students' homes. Weed, pot, hemp, dope, grass, cannabis, cheeba, herb and chronic are synonyms for the drug which brings bleary-eyed Canadians across the country together over joints, bongs and weed-spiked chocolate brownies. Studies in the 1990s concluded smoking weed was more carcinogenic than tobacco cigarettes, giving authorities (mothers included) another reason to disdain the drug. But the National Institute of Health's most wide-scale study showed that smoking the drug had no cancer-causing consequences. The 2006 study surveyed more than 1,000 moderate-to-heavy weed-smokers. Heavy marijuana smokers who estimated a lifetime use of more than 22,000 joints proved to be no more likely to end up with respiratory cancers than people who never smoked marijuana. Though marijuana does contain carcinogens (cancer-causing agents) like those in tobacco cigarettes, these carcinogens were of no consequence in weed. Scientists speculate the tetrahydrocannabinol, or THC, in weed counteracts the smoke's cancer-causing properties by destroying aging cells. Weed's anti-cancer benefits haven't been proven to be preventative, so researchers urge people not to smoke marijuana to lessen chances of developing cancer. Medical marijuana is used to combat tumors already in existence, not to prevent cancer altogether. But don't be fooled. Just because marijuana hasn't been proven to cause cancer doesn't mean it's a harmless drug. Increasing evidence supports strong correlations between marijuana use and psychosis, especially during teenage years. Psychosis is a psychological term to describe a loss of contact with reality. Hallucinations and delusions characteristic in manic depression and schizophrenia are examples of psychosis. As a psychoactive drug, marijuana is still an object of study and debate among scientists. It has both physiological and psychological addictive properties. Especially when used as a regular sleeping aid or relaxant, marijuana creates drug-dependency, causing withdrawal symptoms of anxiety and restlessness. Social enjoyment aside, I used to think potheads were just lazy types of people who enjoyed being in a weed-daze more than I did. But as I approach my mid-20s and people are starting to drop the drug, I'm noticing those friends of mine who can't seem to quit. Though stoners aren't more likely to get throat cancer than anyone else, I worry about the mental disorders that will come from chronic smoking. I worry about the silent battles so many weed-smokers face, lying awake at night because they're not high. I worry about the good, bright people I've seen sink into weed addictions that are socially regarded as insubstantial and easy to stop. Insomnia and psychosis are heavy consequences for such tiny joints. Don't smoke them into your life. As with any treat - chocolate cake, potato couch sessions, Internet porn - moderation is key. - --- MAP posted-by: Jay Bergstrom
