“Cannibis is NOT harmless, it causes extreme Paranoia, Psychosis, and schizophrenia,”

This is false. According to both the British and American Medical Associations. Cannabis is only associated as a contributory factor among high risk groups which includes teenagers and people with a family history of mental health problems. There is no evidence that cannabis causes schizophrenia. People who are already schizophrenic or have a family history of schizophrenia should not smoke cannabis, as it can worsen their condition, but they should not take any psychoactive drug.
Psychosis is a broad clinical term and covers temporary states as well as long term conditions. Only in rare cases, when long term heavy cannabis use is combined with other drugs, is there any possibility of long term effects. You are deliberately trying to mislead people with the unqualified assertions you make.

“My hubby had psychosis because he smoked dope daily, and his own Mental health doctor explained to him how Cannibis was the cause.”

You have already said on other posts that you husband was also a heavy user of other drugs, like cocaine and speed, drugs that are well known for causing paranoia and long term psychosis, so, I really doubt that your doctor said that cannabis caused his condition. It is far more likely that your husband already had personal problems that he tried to escape with decades of heavy drug abuse. Your husband needs to look at the deeper causes of his mental health problems.

“Wasters don't need any more excuses to get wasted do they?”

Look, it is pretty obvious that you are angry with your husband for his obvious reckless and irresponsible heavy drug use for many, many years. That is no reason to project that anger on people who smoke cannabis in moderation and infrequently.
