Drug addictions kills the pains of ordinary human life as it destroy the emotional and physical pains.

In this article, we will discuss some ways of specific drugs that contribute much to drug addiction or more likely the causes of drug addiction by some popular drugs.
Cannabis compounds are drugs that can contribute greatly on drug addiction. Its main active agent is the THC or the delta-9-tetrahydrocannabinol that affects the process of neurotransmitter and communication. Most drug addicted people tend to enjoy the effects of THC agent as they enjoy the reinforced sensations given by the drugs when being used. However to some non-addicted people, they feel uncomfortableness and anxieties.
The drugs of central nervous depressants can also contribute much on the causes of drug addiction as it releases into the synapses, binds to human receptors and eventually lowers the cell excitability's and slow down the activities of the human brain. These drugs contain barbiturates and benzodiazepines that create long term cellular changes through enhancements of actions of the inhibitory neurotransmitter gamma amino butyric acid or the GABA.
The central nervous systems stimulants are drugs that raise the levels of serotonin and dopamine in the synapses. The dopamine is being released by the brain as part of the reward system wherein you can learn to search for stimuli such as food and sex. Meanwhile the serotonin is a chemical form in the brain that regulates the mood. These stimulants usually block the re-absorption of dopamine after it had been released by the brain and can even physically changes the sensitivities of the receptors.
One drug that affects the nerve cells of the reward pathways in our brain is the Opioid, which is a very similar activity with the stimulants as it produces positive reinforcements while being used. There are also opioid receptors found in the spinal cord, brain and gastrointestinal tract.
