context_page_description: Cannabis consumption refers to the variety of ways cannabis is consumed, among which inhalation and ingestion are most common. All consumption methods involve heating the plant's THCA to decarboxylate it into THC, either at the time of consumption or during preparation. Salves and absorption through the skin are increasingly common in medical uses, both of CBD, THC, and other cannabinoids. Each method leads to subtly different psychoactive effects due to the THC and other chemicals being activated, and then consumed through different administration routes. It is generally considered that smoking, which includes combustion toxins, comes on quickly but lasts for a short period of time, while eating delays the onset of effect but the duration of effect is typically longer. In a 2007 ScienceDaily report of research conducted at the University of California–San Francisco, researchers reported that vaporizer users experience the same biological effect, but without the toxins associated with smoking. Δ9-THC is the primary component when inhaled, but when eaten the liver converts this to the more psychoactive 11-hydroxy-THC form.
context_section_description: Although hashish is sometimes eaten raw or mixed with boiling water, THC and other cannabinoids are more efficiently absorbed into the bloodstream when combined with butter and other lipids or, less so, dissolved in ethanol. Chocolates, brownies, space cakes, and majoon are popular methods of ingestion - which are usually called Edibles |Edibles. The time to onset of effects depends strongly on stomach content, but is usually 1 to 2 hours, and may continue for a considerable length of time, whereas the effects of smoking or vaporizing cannabis are almost immediate, lasting a shorter length of time.
  All of the active constituents enter the body when cannabis is consumed orally. It has been shown that the primary active component of cannabis, Δ9-THC, is converted to the more psychoactive 11-hydroxy-THC by the liver. Titration to the desired effect by ingestion is more difficult than through inhalation, due to the long onset time for the effects.
