Abstract:

Marijuana is the popular name of the plant Cannabis sativa, a weed that will grow wild in most climates. The Cannabis plant contains a chemical known as tetrahydrocannabinol, or THC, which produces the psychoactive effects experienced by users. The THC content of Cannabis varies in different parts of the plant. The greatest concentration is usually found in a sticky resin produced by the plant, known as hashish. Declining concentrations are typically found in the flowers and leaves, respectively. Little THC is found in the stem, roots, or seeds of the plant. The potency and resulting effect of the drug fluctuate, depending on the relative proportion of these plant parts in the marijuana mixture consumed by the user.¹ The most common method of administration is by smoking either the dried flowers and leaves or various preparations of hashish. Marijuana is also occasionally taken orally, typically baked in sweets such as brownies or cookies.²

 

 

 

INTRODUCTION:

Narcotic A drug that induces sleep and depresses vital body functions such as blood pressure, pulse rate, and breathing rate.

 

Opiates Medical professionals apply the term opiate to most of the drugs properly classified as narcotics. Opiates behave pharmacologically like morphine, which is a painkiller derived from opium—the gummy, milky juice that exudes from cuts made on the unripe pods of the Asian poppy (Papaversomniferium). Although morphine is readily extracted from opium, the most commonly used opium-based drug is heroin, which is produced by reacting morphine with acetic anhydride or acetyl chloride. Heroin’s high solubility in water makes its street preparation for intravenous administration rather simple, and only by injection are heroin’s effects felt almost instantaneously and with maximum sensitivity. To prepare the drug for injection, the addict frequently dissolves it in a small quantity of water in a spoon.^3-6

 

MATERIALS AND METHODS:

Tests for Cannabis

The Duquenois–Levine test is a simple chemical color reaction test initially developed in the 1930s by Pierre Duquénois.

 

To administer the test, a police officer simply has to break a seal on a tiny micropipette of chemicals, and insert a particle of the suspected substance; if the chemicals turn purple, this indicates the possibility of marijuana. 

 

RESULTS AND DISCUSSION:

Different tests were performed for checking the presence of cannabis in biological samples. Cannabis is a hallucinogen.
