The building looked ordinary, with a colorful sign hung above the door: “Solace Meds.” As we stepped inside a small foyer, nothing was ordinary. There were cameras mounted to the ceilings and red warning posters on the walls. “Must be 21 or older.” “One Ounce Limit.” (That’s 28 grams in metric.)
A man sat at a counter with a big sign: “Show Your ID.” People filed past him one at a time as he checked their driver’s licenses before being allowed through the glass doors into the main store.
Because my drug of choice has always been a glass or two of red wine at dinner, I never paid much attention to what was happening in the world of cannabis. But I have just moved to Colorado, one of 11 states where recreational and medical marijuana is now legal. (Thirty-three states have legalized its use for medical purposes only.) Living in a city where at least a dozen “dispensaries” sell marijuana, my curiosity won out.
Once we got inside, I was dumbfounded. Customers were swarming around long glass display cases where dozens of varieties of the dried weed sat in open containers. The walls were covered with hundreds of tins, boxes, tubes and packages of marijuana edibles like candies and mints. I never dreamed this new industry could have exploded into so many diverse products.
I purchased some edibles, since smoking no longer appeals to me. The packages were securely sealed and stapled shut. It is illegal in Colorado to carry opened containers of cannabis in your car.
At home, I did some research. This natural plant has known medicinal properties, so why was it still illegal in so many states?
I learned that it can be harmful in a few different ways. Marijuana affects short-term memory and a person’s ability to handle difficult tasks. With strains of different strengths, it’s not wholly predictable. It affects a person’s reaction time, so driving a car is highly dangerous, and since it lessens inhibitions, risky behavior can result.
An inability to focus and pay attention makes working or studying difficult. THC, the chemical in cannabis that gives you the high, affects timing, movements and coordination, so it dulls athletic performance.
Synthetic marijuana products have sneaked onto the market with reports of more serious reactions like seizures, kidney damage and even death. Legal regulation helps eliminate this added danger.
That evening, after dinner, I ate a marijuana chocolate bonbon and waited. Would it bring on “reefer madness” or a glassy-eyed stoned paralysis? No, there was nothing. Feeling a bit disappointed, I had to acknowledge it didn’t really affect me at all. In time, I’ll probably find the courage for two bonbons. But I am also a little relieved. I really enjoy my red wine.
