There are many types of drugs and they all have similar yet very different ways to harm you. They also fall into two types of dependency categories, psychological and physical. First there are the narcotic drugs. These relieve pain by depressing the central nervous system. The main source of these types of drugs is opium. The drug of choice in this category is heroin. Because heroin has a high solubility in water it causes the street preparation for intravenous administration to be simple yet instantaneous. It produces a high as well as drowsiness, a deep sense of wellbeing but only lasts 3 to 4 hours (Saferstein, 2011 p. 193). Because the effect of this drug last only so long, the user is constantly taking it to feel the high it causes. The more they use this type of drug the more they are going to physically want it. Also there is a high degree of psychological dependence due to the nature of the drug itself. The feelings it invokes makes you want to keep on using it.
Hallucinogens are another type of drug that causes alterations in mood, attitudes, though processes and perceptions. Marijuana is the most sought after hallucinogen. It is a weed that can grow pretty much anywhere in any climate condition. The most potent part of the marijuana plant is its resin. As you move down the plant the potency lowers. Most people use one of the lesser potency’s such as the flowers or leaves. The single most potent of them all is made from the resin into liquid hashish. It contains a THC content of 8 to 20 percent (Saferstein, 2011 p. 196). Marijuana does not have a history of physical dependence although the more you use the higher your psychological dependency can develop, especially in the more potent uses of marijuana. Heavy use can ...

...d in order to do this you need to test the hair. Drugs will become permanently entrapped in the hair’s protein structure (Saferstein, 2011 p.232). These are the three best ways to test for drugs in toxicology screening.
In conclusion all the drugs mentioned have some type of dependency. It all depends on how you use it, how often and for what purpose. If you just try it once and then never again you won’t get that dependency. If though you use it and find that you can’t live without the feelings it causes you will end up with some form of dependency on your drug of choice. Also if you think you can fool someone into thinking you haven’t taken drugs you don’t really know much about them and their dependencies at all.

There are many biological factors that are involved with the addicted brain. "The addicted brain is distinctly different from the nonaddicted brain, as manifested by changes in brain metabolic activity, receptor availability, gene expression, and responsiveness to environmental cues." (2) In the brain, there are many changes that take place when drugs enter a person's blood stream. The pathway in the brain that the drugs take is first to the ventral tegmentum to the nucleus accumbens, and the drugs also go to the limbic system and the orbitofrontal cortex, which is called the mesolimbic reward system. The activation of this reward system seems to be the common element in what hooks drug users on drugs (2).

The psychological reaction, known as a high, consists of changes in the user s feelings and thoughts. Such changes are caused mainly by THC. The effects of marijuana vary from person to person and from one time to another in the same individual. In most cases, the high consists of a dreamy, relaxed state in which users seem more aware of their senses and feel that time is moving slowly. Sometimes, however, marijuana produces a feeling of panic and dread.

Without contrast, the primary reason for drug abuse in individuals comes from the conscious state of addiction. According to Webster’s, addiction is described as “the fact or condition of being addicted to a particular substance, thing, or activity (Hacker, 2011).” Sure, human nature’s desire to conform to peer pressure might cause one to first try a certain drug, but the euphoric mental states found in drugs mentally trap many individuals into becoming dependent upon these sensations. With that being said, these sensations vary depending on the type of drug used.
The addict becomes dependent on the drug. The addict uses it, despite having full knowledge of its harmful effects on health. It is considered a brain disease because it changes the structure and functioning of the brain.There is an uncontrollable desire or craving to consume the drug. Addicted people often engage in compulsive behavior to obtain the drugs. The addicts find if impossible to control the drug intake. In case of drug abuse, people start taking drugs in larger doses than the recommended doses. The addict is not able to discharge his/her day-to-day responsibilities in an efficient manner. It effects both the physical and mental health of the addict. Very often, addicts witness extreme changes in body weight. Very often, the addict stops socializing.Sometimes, drug addiction is also referred to as drug dependency since the addict develops dependency or addiction for a particular
