I need help with conflicting opinions about pot and hostility [View all]

My brother is a white evangelical Christian.........

He told me recently, and then gave me an article to read that equates pot with impulsivity. I thought it probably was bull and I noticed he cited no sources. But today I was speaking with him, (he has lymes and I have heard that medical marijuana can help that) and telling him my story about 2 pain doctors who lost their licenses for pushing opiates, (and also that our cousin and 2 of his kids have died from heroin......from West Virginia)

Anyway, I looked it up and I found a couple government studies saying the same thing about the impulsivity and hostility with pot. I was kind of shocked. I never equate pot smoking with hostility.

So my first thought afterwards was............let's ask the pot smoking hippies!

And that's why I am here!

Here is the basic gist of it.

"Abstract
BACKGROUND
Marijuana use is increasingly prevalent among young adults. While research has found adverse effects associated with marijuana use within experimentally controlled laboratory settings, it is unclear how recreational marijuana use affects day-to-day experiences in users. The present study sought to examine the effects of marijuana use on within-person changes in impulsivity and interpersonal hostility in daily life using smartphone administered assessments.

METHODS
Forty-three participants with no substance dependence reported on their alcohol consumption, tobacco use, recreational marijuana use, impulsivity, and interpersonal hostility over the course of 14 days. Responses were analyzed using multilevel modeling.

RESULTS
Marijuana use was associated with increased impulsivity on the same day and the following day relative to days when marijuana was not used, independent of alcohol use. Marijuana was also associated with increased hostile behaviors and perceptions of hostility in others on the same day when compared to days when marijuana was not used. These effects were independent of frequency of marijuana use or alcohol use. There were no significant effects of alcohol consumption on impulsivity or interpersonal hostility.

CONCLUSIONS
Marijuana use is associated with changes in impulse control and hostility in daily life. This may be one route by which deleterious effects of marijuana are observed for mental health and psychosocial functioning. Given the increasing prevalence of recreational marijuana use and the potential legalization in some states, further research on the potential consequences of marijuana use in young adults’ day-to-day life is warranted.
