Heroin & Lsd
2/17/2013

Heroin is a very addictive drug; that’s the most rapidly acting of the opiates. Heroin is processed from morphine, a substance extracted from the seed pod of certain varieties of poppy plants. It is typically sold as a white or brownish powder or as the black sticky substance known as “black tar heroin.” Purer heroin is becoming more common, most street heroin is mixed with other drugs or with substances such as sugar, starch, powdered milk, or quinine. Street heroin can also be cut with strychnine or other poisons. Because heroin abusers do not know the actual strength of the drug or its true contents, they are at risk of overdose or death.
When heroin enters the brain it is first converted into Morphine and then binds its self to brain receptors which are Opioid Receptors. These receptors control pain and reward perception within one. They are also important for controlling functions which are critical to life such as breathing and blood pressure for example. Heroin overdose usually results in a difficulty in breathing or suppression of respiration and this is a result of the affected area in the brain due to the heroins intervention and reaction to the brain part that controls these functions within the body. Heroin also poses special problems because of the transmission of HIV and other diseases that can occur from sharing needles or other injection equipment. Some short term effects of heroin are warm flushing of the skin, dry mouth, and a heavy feeling in the extremities, which may be accompanied by nausea, vomiting, and itching. Heroin crosses the blood-brain barrier after the initial effects; abusers usually will be drowsy for several hours. Mental function is clouded by heroin’s effect on the central nervous system. Cardiac function slows. Breathing is also severely slowed, and sometimes in the case of overdose to the point of death. One of the long-term effects of heroin is addiction. Heroin abusers gradually spend more time and energy obtaining and using the drug. Once they are addicted, the heroin abusers primary purpose in life becomes seeking and using drugs. The drugs literally change their brains. Physical dependence develops with higher doses of the drug. Withdrawing from heroin can be difficult Symptoms of withdrawal include restlessness, muscle and bone pain, insomnia, diarrhea, vomiting, cold flashes with goose bumps and leg movements. Withdrawal symptoms peak between 24 and 48 hours after the last dose of heroin and subside after about a week.

Lsd LSD stands for Lysergic Acid Diethylamide. It is found naturally in ergot, and is a chemical produced by a specific type of fungus that grows on grains like rye and wheat. People take LSD as a hallucinogen and for its ability to alter human perception and mood.

LSD effects usually peak at 2-4 hours and gradually diminishing over 6-8 hours. LSD comes in a variety of forms, In its pure form LSD is a white, odorless crystalline powder that is soluble in water.
