15.1 Marijuana, Your Brain, Your Lungs and Your Life


     The videos on this page are clips from the movie Chronic State.  The first video is about how people who sell marijuana tell us that marijuana is good for our mental and physical health.  The second video has doctors telling us about how marijuana affects mental and physical health.

   In the video below they talk about people who treat PTSD and ADD with marijuana.   I don't see how anyone in their right mind can think that getting a child stoned on marijuana will get that child to pay attention.  Research on the impact of cannabis on young’s people’s cognition found that many of the known learning and memory difficulties — such as slowed processing speed, and difficulties in focusing (paying attention)  — could linger for weeks.  The person in the first video says marijuana helps with those things but the research and common sense tells us he's wrong.

    Soldiers in wars often experience terrible traumatic events and develop psychiatric problems as a result (PTSD).  Some veterans take marijuana to reduce the pain memory of those events cause.   Research has not shown that marijuana helps these veterans in fact it can lead to more psychiatric problems.  However it may help prevent nightmares.



This video below starts with a doctor who says that cigarettes affect the lungs (cigarette use can lead to cancer), alcohol affects your liver and marijuana affects your brain.  He should have said :your brain and your lungs."  According to the Center for Disease Control :

Smoked marijuana, regardless of how it is smoked, can harm lung tissues and cause scarring and damage to small blood vessels.  Smoke from marijuana has many of the same toxins, irritants, and carcinogens (cancer-causing chemicals) as tobacco smoke.

Marijuana users are more likely to become temporarily psychotic and develop long term schizophrenia and paranoid schizophrenia than non-users.  Paranoia leads to violence.

A 2012 paper in the Journal of Interpersonal Violence, examining a federal survey of more than 9,000 adolescents, found that marijuana use was associated with a doubling of domestic violence in the U.S. A 2017 paper in the journal Social Psychiatry and Psychiatric Epidemiology, examining drivers of violence among 6,000 British and Chinese men, found that drug use was linked to a fivefold increase in violence, and the drug used was nearly always cannabis.

George Floyd was a black man who died on May 25, 2020 after a policeman leaned his knee on George's neck to keep him restrained after arresting him.  George kept saying I can't breath.  The policeman Derek Chauvin told him that if you can talk you can breath.  George died there were widespread riots across the United States and Derek Chauvin was sentenced to 22 years in prison.  It is possible that George Floyd didn't die because of Derek Chauvin.  That's because he had 3X the lethal dose of fentanyl in his system.  Fentanyl makes it hard to breath.  In addition George had Cannabis in his system.  That too can interfere with breathing.  Maybe there should have been protests against open border policies that allow fentanyl to flood into the country and legalization of marijuana which may have played a role in George Floyd's death.  In addition George Floyd tested positive for the corona virus which also interferes with breathing.  On May 1, 2023 almost 3 years later, another black man, Jordan Neely died after being choked by a former marine named Daniel Penny.  Jordan was threatening people in a subway car and Daniel held Jordan in a chokehold in order to subdue him.  Jordan died afterwards and Daniel was charged with manslaughter.  Jordan Neely didn’t engage in threatening behavior until he started getting taking k2 (synthetic marijuana) a drug known to increase aggressive behavior.  Not only that k2 makes it hard to breath.  Daniel's chokehold may not be the reason Jordan Neely died but there were demonstrations afterwards anyway.

Marijuana users are more likely to become depressed and commit suicide than non-users.

In the video below some parents speak about what Marijuana did to their children.


Growing marijuana in warehouses takes an enormous amount of energy to provide the equivalent of sunlight.  Producing just a couple of pounds of weed can have the same environmental toll as driving across America seven times .  Energy use inevitably produces pollution.
