Opiates are derived from the poppy plant. Opioids are synthetic (man-made) or partially synthetic substances that are engineered to act as an opiate would. These can come in pill form, liquid and powder. There are several ways they can be used-oral (swallowed), inhaled (snorted) and/or injected. Please see the following website for more information.
