Quoting Trent W. Buck (trentbuck@gmail.com):
anaesthetic, n. 1. A substance that causes reversible loss of sensation or loss of consciousness; used to perform surgery without pain.
Yesterday, I took an ibuprofen (on account of almost all my muscle groups saying 'Hullo, you did a great deal of garden work this weekend, and we thought we'd let you know we noticed').
narcotic, n. 1. Any class of substances or drugs, that reduces pain, induces sleep and may alter mood or behaviour.
Last night, I had a nice glass of 10-year-old tawny port.
drug, n. 1. (pharmacology) A substance used to treat an illness, relieve a symptom, or modify a chemical process in the body for a specific purpose.
Today, I drank coffee (very strong, black).
2. A psychoactive substance, especially one which is illegal and addictive, ingested for recreational use, such as cocaine.
I believe I inhaled some second-hand cigarette smoke. I'm just an incorrigible drugs user, aren't I? Back to the Scary Devil Monastery go I. Actually, I believe I'll be summoning up all of my depravity as a drugs user and ingesting a big dose of 8-Methyl-N-vanillyl-trans-6-nonenamide aka capsaicin, via several ripe jalapeno, anaheim, serrano, and hot portugal peppers I just harvested from my garden and will be including in tonight's fresh salsa. The hot portugal peppers are new this year and sensational. I'll be saving seed. http://www.smartgardener.com/plants/2370-peppers-hot-portugal-hot-pepper-og/...
