When I was 16, my first vacation to Europe surprised me. But at the end of the trip for a long time to stay with me rather than the Eiffel Tower, Buckingham Palace or canals of Venice, but ordinary aspects of life: the locals take for granted the things: road marking and the color of the logo, posters, a local snack food in the shop window, and the place of the sound and the smell of the most important.
Drugs have been used for millennia in their natural form. It is not until the 19th and 20th centuries that we have been convinced to shun them and take medication in a synthesized form by drug companies. Most of us would probably not recognize the smell of a drug if it hit us in the face (except perhaps marijuana as few people have had a chance to not inhale that at least once). Here is a small list of common drugs and their odors:
Opium: this has a sweet slightly burnt marshmallow scent when it is smoked.
Heroin: burning heroin releases a very strong smell of vinegar. The higher the quality the less the odor, but all forms will smell to a certain degree. It smells this way because heroin is produced from opium in a method that leaves behind vinegar as a waste product. It is the vinegar smell that drug dogs are seeking.
Cocaine: This primarily smells of methyl benzoate, a floral chemical that gives tuberose its rich smell and feijoas their distinctive taste. Drug dogs sniff for this chemical along with vinegar as previously mentioned.
Methamphetamine: Meth (and crack) both smell similar to burnt plastic combined with cleaning products like glass cleaner. Frequent use can lead to a person’s skin smelling of ammonia. Delightful.
