_Testing Memory Loss from Marijuana Abstinence
_
There is a lot of nonsense spread about harmfulness, tar, etc., as it is about marijuana. If marijuana is 10 times as much tar as tobacco is one of those myths that opponents of cannabis sent into the world. It's all something less simplistic. Remember that a pack of cigarettes smoked per day is 25 times the burned plant material inhaled as the average marijuana smoker for about one gram of cannabis per day. Marijuana can also be vaporized, thus marijuana vaporizer, causing the majority of the harmful substances it is inhaled, not even arises, but without the psychoactive effects to undo.
Moderate regular use of cannabis impairs the memory and attention
Researchers found no difference in performance between non-users and moderate regular cannabis users for a week that had not used in memory tests and selective attention. They also found no difference in overall patterns of brain activity, measured with fMRI (functional magnetic resonance imaging). However, a significant change is noted in a small part of the left cerebral cortex. Regular cannabis users had in their lives between 675 and 5,400 cannabis cigarettes smoked between 75 and 900 (average 350) during the past year. Non-users smoked during their lifetime between 0 and 15 cannabis cigarettes. In the memory test, participants had five consonants remember. Later consonants are presented to the subjects and they had to press a button when a consonant from the list appeared. In the test on selective attention, participants had to determine whether the tone they heard was lower or higher than a specified base tone. In a similar test they had to determine whether a dot is larger or smaller than a previously displayed dot.
Researchers concluded that no evidence found for deficits in long-term working memory and selective attention in frequent but relatively moderate cannabis users after 1 week of abstinence. However, they noted that not all effects of cannabis on the brains can be excluded because there is a difference in the activity of some of the brains involved in working memory. Most previous studies focused on extremely heavy use and this is not representative of the majority of recreational marijuana vaporizer and cannabis use.
