Injected pot by a vape unit gives a more powerful high ̵
1; and often more harmful side effects – than the smoking version, finds a new study.
At the same level of THC, the psychoactive ingredient in marijuana led to increasing blood concentrations of the chemical than smoking, as well as higher levels of cognitive and psychomotor impairment and a higher incidence of side effects such as vomiting, anxiety, hallucinations and feelings of paranoia, according to the report, published Friday in JAMA Network Open.
It is important to understand the effects of vaping as more and more states legalize cannabis and the drug becomes readily available, says the study’s leading author, Tory Spindle, a postdoctoral researcher at Johns Hopkins School of Medicine. “More people come to cannabis dispensers and use for the first time for a while or for the first time ever,” said Spindle for NBC News. “They should be aware that vaping will produce stronger effects. We found that there was a fine line sometimes between a dose that gave the desired effects and the one who was too strong.”
The study comes out as more and more Americans uses pot, including teens. In fact, a new study showed that as many as 1 in 11 rub cannabis, while another reported that cannabis has more harmful effects on developing brains than alcohol.
In order to get to know the effect of raping cannabis, Spindle and his colleagues rounded off 17 intermittent pot smokers whose average age was 27. Most had not used cannabis for a long time. on average it had been almost a year.
All study volunteers conducted three eight and a half hour sessions during which they smoked marijuana at three different THC doses (zero milligrams, 10 mg and 25 mg) and three where they wiped the drug at the three different doses. The sessions were scheduled to be a week apart. The zero-milligram dose served as control in this study.
When volunteers had vaporit or smoked cannabis, their cognitive and motor skills were tested. They were also invited to fill in a questionnaire that assessed the extent to which volunteers felt the following: drug effects; nice drug effects; unpleasant drug effects; ill; cardiac run; anxious and / or nervous relaxed; paranoid; warn; irritable; powerful and / or motivated; restless; hungry and / or had the munchies, sleepy dry mouth; dry, red and / or irritated eyes; throat irritation and / or coughing; difficulties in performing routine memory damage; and requests from cannabis.
In both doses without dosing, the impact of cannabis was greater when it woke up than when smoked found researchers. However, at higher doses, Vapers experienced more adverse side effects. “Two people were vomited from the high dose,” Spindle said. “You actually experienced sound and visual hallucinations. Some experienced paranoids too. So it’s not just about impairment.” The negative effects can be quite unpleasant. “
Spindel suspects that stronger effects are felt during weaponry, mainly because none of the material is lost for combustion. “The difference is probably due to some destruction of the drug when cannabis burns, which does not happen when it is vaporized,” he said.
Evidence that guns have a stronger impact than smoking is important, says Dr. Michael Lynch, head of the Pittsburgh Poison Center at the University of Pittsburgh Medical Center.
“People often create an equivalence between smoking and smoking, provided that if you use the same amount of drugs the effects will resemble,” Lynch said in an interview. “I think this helps to inform people who will use it medical or recreational so the effects are not the same and the same dose can lead to more negative or negative effects.”
Lynch is particularly concerned about his teens. “Young people are more likely to vape than smoking,” he said. “Data that comes most from nicotine use shows that vaping is a fairly common way that teens are first exposed.”
Another concern to remember, Lynch said, it’s what teens start driving, “they have to understand that these drugs are intoxicating. We have definitely seen increases in drug-inducing injuries and deaths.”
There are many misconceptions regarding vaping, says Stan Glantz, Professor of Medicine and Head of Center for Tobacco Control Research and Education at the University of California, San Francisco.
“It’s an assumption that since you do not put the substance on fire, it’s not that bad,” says Glantz. “It does not turn out to be true. Delivering a higher dose of drug gives vaping an aerosol of ultrafine particles sent to the lungs and then the brain. These particles are very small, a 50 to 100 hair size. They can pass through the lungs and into blood and from there into the cells of the body. “
