It is important to understand the effects of vaping as more and more states legalize cannabis and make the drug more accessible, according to study lead author Tory Spindle, a research associate at the Johns Hopkins School of Medicine. "More people are coming into cannabis dispensaries and are being used for the first time in a while, or for the first time ever," Spindle told NBC News. "You should be aware that steaming causes stronger effects. We found that there was sometimes a fine line between a dose that produced the desired effects and too high a dose.
The study comes to light as more and more Americans use pot, including teenagers. A recent study even found that 1 out of 11 cannabis vaporizes, while another reports that cannabis has more damaging effects on brain development than alcohol.
To learn more about the effects of cannabis vaporizing, Spindle and his colleagues rounded 17 intermittent smokers with an average age of 27 years. Most had not consumed cannabis for a long time. on average, it had been almost a year. All volunteers completed three and a half hour sessions of smoking marijuana in three different THC doses (zero milligrams, 10 mg, and 25 mg) and three by degassing the drug in three different doses. The sessions should be one week apart. The zero milligram dose served as the control in this study.
After the volunteers steamed or smoked cannabis, their cognitive and motor skills were tested. They were also asked to complete a questionnaire to assess the extent to which the volunteers felt that they felt the following: drug reactions; pleasant drug effects; unpleasant drug effects; Sick; Palpitations; anxious and / or nervous; relaxed; paranoid; to warn; irritable; strong and / or motivated; restless; hungry and / or had the munchies, sleepy; dry mouth; dry, red and / or irritated eyes; Throat irritation and / or coughing; Difficulty in performing routine tasks; Memory impairment; and craving for cannabis.
At both non-zero doses, the influence of cannabis in vapors was greater than in smoking, researchers found. At the higher dose, however, Vapers had other negative side effects. "Two people have vomited from the high dose," said Spindle. "There have actually been some auditory and visual hallucinations. Some also experienced paranoia. So it's not just about an impairment. The negative effects can be quite uncomfortable.
Spindel suspects that stronger effects are felt when steaming, mainly because no material is lost through combustion. "The difference is most likely due to the drug being destroyed by the burning of cannabis, which does not occur during evaporation," he said.
Evidence that vaping is stronger than smoking is important, said Dr Michael Lynch, director of the Pittsburgh Poison Center at the University of Pittsburgh Medical Center.
"People often create an equivalence between vaping and smoking, assuming the effects are similar for the same amount of drug," Lynch said in an interview. "I think this helps inform people who use it medically or for recreational purposes, that the effects are not the same and the same dose could lead to more negative or detrimental effects."
Lynch is particularly worried about teenagers. "Teenagers tend to smoke rather than smoke," he said. "Data, mainly from nicotine use, shows that vaping is a fairly common way in which teens are exposed for the first time."
Another concern to note is the fact that young people, when they start driving, need to understand that these drugs are understood to be intoxicating. In any case, we have seen an increase in drug-related injuries and deaths. "There are many misconceptions about steaming," said Stan Glantz, professor of medicine and director of the Center for Tobacco Control Research and Education at the University of California, San Francisco.
"There is a presumption that it is not so bad if you do not set the substance on fire," said Glantz. "That's not true. At a higher dose of the drug, vaporization creates an aerosol of ultrafine particles that are sent into the lungs and then into the brain. These particles are really small, 50 to 100 times the size of a hair and can go directly through the lungs into the blo and from there into the body cells.
