@rosiejaune Not true. Marijuana can act as a depressant and is believed to be a possible risk of increase of alzheimers. It is not the 'safe' and 'harmless' drug people think it is.
Further info about Marijuana;
^Marijuana is a depressant drug that slows down the messages to and from your brain. The active ingredient in marijuana is tetrahydrocannabinol (THC). Marijuana might make you feel ‘chilled out’, relaxed, happy and chatty, and may lead to hallucinations if a large dose is taken.
Marijuana also has many negative effects. It causes slower reflexes, poor coordination and concentration, nausea, glassy eyes and increased heart rate and appetite.
Regular users can get chest infections, lower sperm count, irregular menstrual cycle and lowered sex drive. They can become dependent.
There is also some evidence that cannabis can produce psychotic symptoms in people with a family history of mental illness. It can also make psychotic symptoms worse and harder to treat if you already have a mental illness like schizophrenia.
Marijuana users can have social and financial problems, and don’t do as well in education.
Problems are more common for people who start using marijuana at early age, and for people who use it regularly.^
and
^It’s a commonly used recreational drug, but does marijuana cause Alzheimer’s? This is a question a lot of people have, especially since last year there was a study released showing that marijuana can increase susceptibility to Alzheimer’s.
The study was published in the Journal of Alzheimer’s Disease, and it showed that people with a marijuana use disorder had reduced blood flow in almost every area of the brain, compared to controls who didn’t use marijuana. The research showed the hippocampus area of the brain had the biggest reduction in blood flow because of marijuana. The hippocampus is the part of our brain associated with memory and learning, and in people who have Alzheimer’s, it’s the first area of the brain that’s affected.
When you use marijuana, and it reduces blood flow to the brain, it reduces the amount of oxygen that can reach brain cells, which can result in damage to the tissues and even death.
Researchers believe that marijuana also blocks activity in the brain which prevents the formation of memories.
The results of this study don’t show definitively that marijuana can cause Alzheimer’s, but it should give marijuana users a bit of hesitance.^
There are too many red flags with cannabis, it's not the safe and harmless drug people think it is.
Either way, OP, it's clear your BFs problems with being organised in life is linked to his regular marijuana use. It's clearly interfering with his life and will interfere with his ability to become a teacher and hold down his job. You need to decide if you can be in a relationship with someone with such a dysfunctional life.
