Marijuana is typically smoked or eaten. The crushed leaves are usually rolled into a "joint" using a cigarette paper, or smoked from a pipe or bong (a large pipe filled with water or wine). Less commonly, the leaves are rolled into a "blunt" using an emptied cigar, sometimes mixed with cigar tobacco and/or another drug. Finely ground marijuana leaves are often baked into brownies or cookies (for portability and discretion) or whole leaves are brewed into a tea.

Passive inhalation . In general, routine passive exposure to marijuana smoke will not result in a positive result for carboxy-THC. Only under unrealistic conditions, a person may test positive for carboxy-THC, but concentrations are generally below the routine cut off levels.
Marijuana, hashish , charas, Ganja, bhang, kef, and dagga are names that have been applied to various regional preparations and varieties of the cannabis plant. Hashish, the most potent of the cannabis preparations, was named after its Persian founder, Hasane Sabbah. After preparation is complete, Hashish is a light to dark brown (the darker the shade, the stronger the potency), clay-like substance and about eight times as strong as the marijuana typically found in the United States. In North Africa, hashish is commonly eaten or smoked in a water pipe (the water cools the smoke). Cannabis plants that are rich enough in the resins that produce hashish are indigenous to only a few regions of the world. In India, the cannabis resin is typically powdered and sifted and is called 'charas'.
Ganja, prepared from cannabis plants cultivated in India, is one of the more potent forms of cannabis, but less potent than hashish or charas because it contains less resin. Ganja is prepared like charas, but produced from the flowers, leaves, and stems, and twigs. Because almost the entire plant is utilized, Ganja has less resin and consequently less potency.
Bhang is a preparation of cannabis drunk in Hindu religious ceremonies across India. Because it does not contain the cannabis flowers, bhang has less resin and is therefore less potent than Ganja. A less powdery� form of Bhang can be smoked. Marijuana found in the United States is similar in potency to Indian bhang.
