One is bad, and the other is mud that can't support the wall. Old Bai himself, living in his own world, has no ability to think in other ways. The younger brother received is like A Dou, he does things in a disorganized manner, and his life has no goals and plans. He didn't know what situation he was in, didn't know the boundaries of what he should do and shouldn't do, and he didn't have any responsibility. When I went to intimidate, I actually played with the child. was also countered. What a mess.
Talk about drugs.
The drug Lao Bai made was ice. One of the Big Three.
Heroin, morphine derivatives, sedatives. Acts on opioid receptors. Feeling euphoric after use. Side effects, respiratory depression, digestive system depression.
Ice, stimulants. Similar to dopamine. Side effects, damage to the mouth, can trigger paranoia and delusions.
Cocaine, a dopamine reuptake inhibitor, increases dopamine levels. Stimulant.
Withdrawal responses vary widely among the three drugs. The opposite of sedation is anxiety, morphine also has analgesic effects, and the opposite is pain.
The opposite of excitement is depression, apathy, and low spirits.
This should explain why physical abstinence from heroin is the most difficult.
Drugs can be divided into sedatives, stimulants and hallucinogens, guessing that alcohol is biased towards stimulants, while nicotine is biased towards sedatives. So nicotine withdrawal is also more difficult. (I checked the information and did not support the speculation that nicotine is biased towards sedatives. On the contrary, it is believed that nicotine is related to dopamine) (I didn't say it, and alcohol does not support this)
The main manifestation of methamphetamine psychosis is delusions. Schizophrenia is thought to be related to disturbances and hyperactivity of the dopamine system.
The cycle of bipolar disorder behaves a bit like the drug-withdrawal process.
Both addiction and tolerance should involve the regulation of sensory sensitivity. In order to adapt to diverse environments, the sensitivity of biological nerves is constantly adjusted. For example, an environment that requires alertness may increase the sensitivity, and an environment that requires patience and courage may require a decrease in sensitivity. These involve neurotransmitter and receptor interactions.
When exotic psychotropic drugs disrupt this balance, the body automatically seeks to rebalance. Taking morphine as an example, the intake of morphine will make the body think that the secretion of endorphins is too much, so it will reduce its secretion and the sensitivity of its receptors. In this way, tolerance develops. When foreign opioids are no longer ingested, the body will lack endorphins and opioid receptors will be too insensitive. In this way, the sensitivity of negative sensory systems such as pain will be very high, and even the original noise signal will be regarded as effective. lead to withdrawal symptoms.
From this point of view, heart addiction is not an addiction in essence, it is just a memory.
Coca-Cola, cocaine, coca, these words actually have the same part, but the translation is different. Cocaine is the ancestor of local anesthetics, and many local anesthetics ending in caine were born from it.
Cocaine, heroin, caffeine, codeine, etc., the cause here refers to alkaloids. It seems that various alkaloids are often present in plants. Therefore, no matter what the material of traditional Chinese medicine is, almost all have a bitter taste. (So bitter taste is also a kind of biological self-protection to prevent ingestion of strange alkaloids)
