Tolerance: a state in which an organism no longer responds to a drug. A higher dose is required to achieve the same effect. Withdrawal: abnormal physical or psychological features that follow the abrupt discontinuation of a drug that has the capability of producing physical dependence. For example, common opiates withdrawal symptoms include sweating, goosebumps, vomiting, anxiety, insomnia, and muscle pain. Low risk drinking guidelines: drinking is a personal choice. If you choose to drink, these guidelines can help you decide when, where, why and how to drink safe, responsibly and to keep risks at a minimum. They are used to reduce long-term health risks, to reduce risk of injury and to reduce harm. Neurotransmitters: neurotransmitters are chemicals located and released in the brain to allow an impulse from one nerve cell to pass to another nerve cell. Neurotransmitters can excite or inhibit neurons (nerve cells). Acetylcholine and norepinephrine are excitatory neurotransmitters while dopamine, serotonin, and gaba are inhibitory.
