They legalized marijuana years ago in my state.  The amount of overdoses from it are zero, while we would see heroine and fentanyl every day in the hospital.

 With legalization thus far there has not been an increase in suicide, crime or vehicle deaths, however chronic narcotic use is down.  The initial concerns that legalized recreational marijuana would cause an increase in ER visits has not materialized, there has actually been a reduction due to many chronic pain relief seekers and cancer patients finding resolution in CBD and other marijuana related substances.

 I personally had no opinion regarding marijuana other than it should be treated like alcohol, no public consumption, and must be of age.  I wasn't sure what the results would be, but so far there has been no increase in medical care needs (actually a decrease) and no crime increase, so I can't say marijuana is much of an influence other than the huge economic impact.

 I can probably get you some official statistics from the Dept of Health and Human Services, if you think those are not part of some cover up.

 I did not say there were zero crime or vehicle deaths associated with marijuana, I said there were zero overdoses.  Its very hard to overdose on.  Synthetics are different though.  Vehicle related deaths since the introduction of legalized, and then recreational marijuana have not increased, while the consumption rate has dramatically.  This means vehicle related deaths attributed to marijuana have not increased at the rate of consumption, or even remotely close to alcohol or meth etc.  Same goes for crime - there isn't an increase in overall crime that correlates significantly with the millions of marijuana users.

 To clarify "chronic narcotic use" is different than chronic narcotic abuse.  Drug abusers taking heroine are not reducing their heroine consumption by using marijuana.  People with chronic back pain, cancer patients, high anxiety dysfunction are examples of people who are having less prescribed narcotic medication due to marijuana consumption.

 "chronic pain relief seekers and cancer patients " as indicated in the previous post are not intended to include someone satisfying a drug addiction through heroine.

 There extensive documentation regarding the distribution of pain-treatment narcotic prescriptions in cancer patients.  This information may be made available, again if you don't consider the medical records part of a marijuana statistics cover up.
