I smoke a join and no feel good at all!!what can i do to reduce the effects?

Vit C, Nux, music: I don't know how you're feeling but many people do not react well to marijuana (though reactions can vary with diff. strains). Any adverse reaction will go away within a few hours. Vitamin C and B vitamins may help (esp. niacineamide). Homeopathic Nux vomica may help- available at health food stores & some pharmacies. Listening to music you enjoy and slow deep breathing may help you feel better.
