Fact:
Aside from the possible elevated risk of cancer due to smoking, many other studies have looked into the possibility that marijuana(cannabis) use can trigger other illnesses such as heart disease, bi-polar disorder, depression, mood swings or schizophrenia, typically in individuals with a diathesis for these illnesses. More research is no guarantee of greater consensus in the field of marijuana studies, however: both advocates and opponents of the drug are able to call upon multiple scientific studies supporting their respective positions. For instance, while marijuana has been correlated with the development of various mental disorders in multiple studies, these studies differ widely as to whether marijuana use is the cause of the mental problems, whether the mental problems are augmented by marijuana use, or whether both the marijuana use and the mental problems are the effects of some other cause.

Father, I pray for this son's salvation. Send a godly spirit filled Jesus believer to minister to this young man and reveal to him the gospel of Jesus Christ if he is not saved. Father, use him for your purposes for your glory through your son our Lord Jesus. Amen.
