What is Heroin Tolerance

heroinJust using drugs a few times can be bad all by itself. You’re inhaling or ingesting (eating) toxic substances that the human body has not evolved to deal with. As a result, we see strange results whenever the body takes in something like heroin, cocaine or marijuana.

Our early ancestors probably looked at these bodily reactions as simply being poisoned (little did they know how right they were.) Over time, they probably imagined that the gods were striking them down or otherwise interfering with their lives.

In modern day, we have changed to the point where instead of being repelled by these drug reactions, many people all around the world actively pursue them. It’s strange to think about, but there are people all over the world, young and old, that actually want to poison their bodies with alcohol till they get blackout drunk, or take LSD until their bodies react with violent hallucinations.

This is a symptom of decay across the world’s cultures, and you’d be right to think that it’s bad all by itself. Even worse, however, is the fact that continued drug use builds up a “tolerance,” and that leads to needing to take even more drugs than before.

With the use of heroin reaching epidemic levels in the United States, it is vital that we examine the issue of what exactly heroin tolerance is and how it can affect the lives of Americans in communities across our country.

Tolerance is a Physical Reaction

When a body first experiences a drug, it will react with the full response of an organism experiencing a poison. If the body continues to experience that same poison, however, it will try to overcome the negative effects it is experiencing. In other words, over time that same amount of drug will not have the same reaction on the user. This is called “tolerance.”

For example, the first time someone takes a puff of marijuana, he will probably feel a huge rush (in addition to a gigantic fit of coughing.) He might think he really likes the experience (despite the damaging effects on his mind and body), so he will try to use it again and again in order to get that same high.

The problem is that from the very first time he tries the drug, his body is going to start fighting to keep itself from getting poisoned. It will try to mitigate the effects of the drug, so he won’t get quite as high as before. He will then probably try to take more of the drug in order to “chase” that first high, but he’ll never quite get there.

Heroin Tolerance is Incredibly Dangerous

The danger isn’t quite as high with a drug like marijuana because it is almost impossible to overdose on the drug. With heroin, however, it’s a completely different story. Heroin users build up a tolerance over time, too, but it is very easy to overdose on this drug. The addict will try to chase that original high, but he will have to take very high doses of heroin in order to get there.

Heroin is a nervous system depressant that can lower your heart rate and breathing rate. If you take too much, it can actually stop you from breathing completely. Most heroin overdoses occur when the addict is trying to chase a high and accidentally takes far too much of the drug. His breath stops completely, he passes out, and he never wakes up.

If you observe anyone you know using heroin even once, help them to get professional rehab help immediately. Even a few uses can be too many.
