Name the drug that fits each clue.
- A white, odourless, bitter, crystalline compound, made by the acetylation of morphine, and taken by snorting or injection.
- A substance from a South American plant that interferes with the transport of dopamine and gives a feeling of euphoria.
- A preparation from the resin, the leaves and the flower tops of a plant, taken by inhalation or by the mouth.
- A very effective painkiller that doctors give after surgery, and that comes from the latex of the poppy.
Need a reminder? The key ideaShow
Opioids, cannabinoids and coca alkaloids are the commonly abused drugs. Morphine comes from Papaver somniferum, and heroin is made from it by acetylation. Cocaine comes from Erythroxylum coca. In smoke, nicotine raises the blood pressure and the heart rate, and carbon monoxide binds to haemoglobin. Each gram of free haemoglobin carries about mL of oxygen.
