The onset of the drug is almost immediate. It is very smooth going down to exprienced users. for someone whom hasnt used the drug before or often might find it bitter as the drip hits. I do not recommend using oxycontin at all as it is very very addictive. Also if you snort the pill you are more prone to vomiting shortly thereafter. You will start itching and feel VERY euphoric. You will also become constipated and usually won't deficate for 24-48 hours after getting high. It is an incredible feeling that lasts for hours. You must know your own body and tollerance before deciding to snort a pill. DONT DO IT. you will regret knowing what these magic pills taste and feel like.
