Many of these "research chemicals" cause cancers and other illnesses such as respiratory problems, weakness, demonic voices (suicidal thoughts) and more.. Stick to marijuana that God made.. which cures cancer and benefits victims of parkinson's, alzheimer's, epilepsy and infinite other diseases.  Take advice from me and do not try "spice" or any of the other pharmaceutical trash out there.. stay away from pills.. take natural vitamins, eat healthy, exercise and praise Jesus Christ.  Pharmaceuticals are sorcery (witchcraft) and will bring bad things to your life and nothing good.
