“There is a wide range of concentrations of metals contamination in these products from a relatively low level to grossly contaminated,” researchers noted.
Before you roll your next joint, listen up. An analysis conducted on rolling papers showed that there was at least one heavy metal in 90% of the papers that were tested. And according to data, 8% of them contained at least one heavy metal in concentration levels above the allowable state limits for cannabis products.
Researchers from one of California’s leading cannabis labs, SC Labs, analyzed samples of 70 rolling papers — 25 pre-rolled cones, 20 wraps and three cellulose based papers, all purchased from Amazon and different smoke shops located throughout Santa Cruz.
“It is not surprising to find a prevalence of heavy metals detected in the rolling paper products and should not be considered alarming on its own,” researchers noted. “There is a wide range of concentrations of metals contamination in these products from a relatively low level to grossly contaminated.”
While it may be surprising to learn that there’s metals in your rolling papers, it makes sense. Paper is made out of plants, which naturally absorb contaminants from the soil that they were planted in. Although rolling paper manufacturers have to adhere to some regulations, including listing their ingredients, these are generally less monitored than other products within the tobacco and cannabis industry.
There will always be some level of harm associated with smoking any kind of paper, which makes switching to other cannabis consuming methods a valid option. If you enjoy your joints, you can still try to keep yourself as healthy as possible by sticking to popular and certified rolling paper brands, such as RAW.
Avoid purchasing bleached and thick papers, since these have more contaminants, produce more smoke and, thus, more harm to your lungs. Also, avoid blunt wrappers and colored papers. Like everything else cannabis related, always be on the lookout for the most natural ingredients.
