A joint or spliff rolled from the roaches of other joints or spliffs so nipes are usually a last resort method of getting stoned. The disgustingness of a snipe will depend on the quality of the roaches you find, but while there can be a noticeable difference between a bad snipe and a really bad snipe, there is no such thing as a good snipe. Avoiding them is recommended.
