Its physical effects include disturbed sleep patterns, Nausea, and Bizarre, erratic, sometimes violent behavior. Methamphetamine increases the amount of dopamine, which results in increased chemicals in the brain. Methamphetamine is a dopamine agonist. Caffeine is a CNS stimulant. It is the world’s most consumed drug. Some physical effects include high blood pressure, rapid heartbeat, and hyperglycemia.

Some physical effects include heart disease, stroke, and depression. The nicotine molecule is shaped like a neurotransmitter called acetylcholine. Acetylcholine and its receptors are involved in many functions, including muscle movement, breathing, heart rate, learning, and memory. They also cause the release of other neurotransmitters and hormones that affect your mood, appetite, memory, and more. When nicotine gets into the brain, it attaches to acetylcholine receptors and mimics the actions of acetylcholine. (How Does Nicotine Act in the Brain? 2015) Nicotine is an agonist to ACH. Cocaine is a highly addictive drug synthetically derived from coca. Some physical effects of cocaine include increased heart rate, body temperature, and increased rate of breathing. Normally, dopamine is then recycled back into the transmitting neuron by a specialized protein called the dopamine transporter. If cocaine is present, it attaches to the dopamine transporter and blocks the normal recycling process, resulting in a buildup of dopamine in the synapse, which contributes to the pleasurable effects of cocaine.
