Hash Oil

Hash oil (also known as hashish oilBHOwaxsativa bhoindica bho,[1] full melthoney oil,[1] dabs, or budder) is a form of cannabis. It is a resinous matrix of cannabinoids obtained from the Cannabis plant by solvent extraction,[2] formed into a hardened or viscous mass.[3]

Hash oil can be the most potent of the main cannabis products because of its high THC content, which can vary depending on the plant.[4]

Reported THC contents vary between sources. The 2009 World Drug Reports reports THC content as “may exceed 60%”. A 2013 American forensic science book gave a range of 10–30% delta-9 THC by weight.[5] and a 1972 American forensic journal reported a range of 20–65%.[6] current testing labs regularly report oil potencies ranging from 30% to 90%, with levels of dispensary quality oil typically ranging from 60% to 85%, occasionally higher and occasionally lower. Some extracts have supposedly been tested to over 99% THC but involve a multiple stage chemical process.


Hash oil can be consumed in various ways, including dabbing, smoking, vaporization, or oral consumption (eating).[7] Typically, it is vaporized in what is known as an “oil rig”, a small water pipe designed for hash oil vaporization. The user takes a hand-held blowtorch (USA usage) / blowlamp (UK usage) and heats a titanium, quartz, borosilicate, or ceramic surface until the surface, which can be a nail or a skillet, reaches the desired temperature indicated by a glowing orange hue. Recently, quartz and ceramic have been popular replacements for titanium. This is followed by placing a drop of hash oil, a process known as “dabbing”, on the hot surface with a glass or dental pick until it melts, boils, and vaporizes through the water pipe and into the user’s lungs.

The Dangers

Marijuana and hashish products contain cancer causing elements (carcinogens), just like cigarettes. Although marijuana is seldom smoked with the same frequency as tobacco, it can lead to upper respiratory problems such as those caused by cigarette smoking.

Hashish use as a medicine and recreational drug dates back to at least the 3rd millennium BC.

What MDherb says…

The tetrahydrocannabinol (THC) content of hashish comes in wide ranges from almost none to 70%, and that of hash oil from 30–90%. Hashish color usually reflects the methods of harvesting, manufacturing, and storage. Hash ranges from very light beige and tan to dark brown and black, usually depending on production methods. A green tinge indicates that the hashish contains a large amount of leaf material, but this is only relevant to improper production.

Hashish come from the hemp plant, cannabis sativa, which grows throughout most of the tropical and temperate zones of the world. Marijuana is typically sold in the form of cut, dried leaves, stems and flowers of this plant. It is generally smoked like a cigarette or cigar, or in pipes. Sometimes it’s eaten.
Hashish is the dried, caked resin from the hemp plant flower and is generally smoked in pipes. Hashish oil is extracted from the hemp resin

The main active chemical in marijuana is THC (delta-9-tetrahydrocannabinol). Marijuana’s effects on the user depend on the strength or potency of the THC it contains. Hashish contains the same active ingredients as marijuana, like THC and other cannabinoids, but with higher concentrations. THC has been used to treat wasting syndrome in AIDS patients.
