Hashish, or hash, is a concentrated form of cannabis made from the plant’s resin, and it is not the same thing as marijuana flower. The resin is where the plant’s cannabinoids are most concentrated, so hash is generally stronger by weight than the buds it comes from. Legal hash is sold by licensed stores in Washington and Oregon as a concentrate.
People often hear “hash” and picture a brown block from a movie. In practice the word covers a range of products, from traditional pressed resin to modern solventless extracts. This guide explains what hashish is, how it differs from marijuana, the main types, how people use it, what the risks are and how to buy it legally. It is general information for adults.

What Is Hashish?
Hashish is cannabis resin that has been collected and usually pressed or shaped. The National Cancer Institute’s cannabis summary explains that the plant’s resin contains cannabinoids, the family of 21-carbon compounds that includes THC and CBD, and that their concentration is highest in the female flowers. Hash collects that resin and leaves most of the plant material behind.
The product is typically a paste or solid with a texture that ranges from soft and pliable to hard and brittle. Color varies from light tan to dark brown or nearly black, and some hash looks reddish or greenish. Color and texture depend on the plant, how the resin was collected and how the hash was stored.
Hash vs. Marijuana: What Is the Difference?
Both come from the same plant and both contain THC, the compound NIDA identifies as the one with intoxicating, mind-altering effects. The difference is form and concentration.
- Marijuana (flower): the dried flowers and leaves, smoked or vaporized as plant material.
- Hash: the resin collected from the plant, which is a concentrate.
Because hash is a concentrate, a small amount can deliver a lot of THC. NIDA notes that the THC potency of illegal cannabis seized by law enforcement rose from 3.96% in 1995 to 16.14% in 2022, and that flower and concentrates in dispensaries can exceed 40%. Check the label rather than guessing from appearance.
Types of Hash
- Traditional pressed hash: resin gathered by hand or by sifting and then pressed into blocks or balls. Region names such as Moroccan or Afghan describe where a style comes from. See our guide to charas, a hand-rubbed style from South Asia. Large loads still move by sea: in 2013 the cargo ship Gold Star burned off Malta with about 30 tons of hashish aboard.
- Kief and bubble hash: loose resin collected by sifting, or resin separated using ice water. Bubble hash is a solventless product.
- Rosin: made by pressing plant material or hash with heat, no chemical solvent needed.
- Ear wax hash: a pliable, wax-like concentrate. See our ear wax hash guide.
- Solvent-based concentrates: sold as shatter, wax or live resin. These are made in licensed labs. Making them at home with butane or propane is dangerous and illegal for unlicensed people; see our dabbing guide.
How People Use Hash
NIDA lists common methods for concentrates: vaporizing or inhaling with a device, and mixing into food. In practice:
- Sprinkled on flower: crumbling a small piece onto a bowl or into a joint.
- Vaporizing: heating a small amount in a device made for concentrates.
- Cooking: hash is sometimes added to food, hence the “hash brownie.” Eaten cannabis acts much later than inhaled cannabis; the NCI reports THC peaks 1 to 6 hours after ingestion. Read our dosage guide before trying edibles.
Inhaled effects begin within minutes (NCI: peak in about 2 to 10 minutes). Start with an amount smaller than you think you need.
Risks of Hash
Hash carries the same risks as other high-THC cannabis, amplified by its strength. NIDA says higher THC concentrations are associated with a greater likelihood of cannabis use progressing to cannabis use disorder. Other documented risks include anxiety and impaired coordination, cannabinoid hyperemesis syndrome after long-term heavy use, and impaired driving. Smoke from cannabis products contains many of the same toxins, irritants and carcinogens as tobacco smoke, according to NIDA.
The CDC warns that concentrated THC products may contain additives or contaminants. That is a main reason to buy from licensed stores, where products are tested, instead of from unlicensed sources.
How to Read a Hash Label
Licensed products in Washington and Oregon carry lab-tested potency. Look for the THC percentage, the total package size and the producer’s name and license information. Because a concentrate can exceed 40% THC, even a pea-sized piece may be a large dose for a new user. If the label does not show test results, do not buy it. Ask the budtender how the product was made, and whether it is solventless or solvent-based, so you know what you are inhaling.
Someone who has never used a concentrate should treat hash as a different product from flower, not as a stronger version of the same experience. Tolerance built on flower does not guarantee comfort with hash, and the NCI notes that effects of inhaled THC begin within minutes, leaving little time to adjust once you have taken too much.
Is Hash Legal?
Cannabis concentrates, including hash, are legal for adults 21 and older to buy from licensed stores in Washington and Oregon. Washington’s possession limit is 7 grams of concentrate; see our Washington marijuana laws and Oregon marijuana laws pages. Cannabis remains illegal under federal law, so do not cross state lines with it. Find a licensed store in our Washington or Oregon directory, and browse more in Cannabis 101.
Hashish FAQ
What is hashish?
Hashish is a concentrate of cannabis resin. The resin holds the plant’s cannabinoids, which are most concentrated in the female flowers, according to the National Cancer Institute.
Is hash the same as weed?
No. Both come from the cannabis plant, but weed is the dried flower and hash is the collected resin. Hash is a concentrate and is usually stronger by weight.
Is hash stronger than marijuana?
Generally yes, because it concentrates the resin. NIDA reports that dispensary concentrates can exceed 40% THC. Strength varies, so read the lab label.
What does hash look like?
It ranges from light tan to dark brown and sometimes black, red or green, and from soft and pliable to hard and brittle.
How do you smoke hash?
People usually crumble a small piece onto flower or vaporize it in a concentrate device. Use a very small amount because the effects are stronger than flower.
Can hash be eaten?
Yes, but eaten THC peaks 1 to 6 hours after ingestion according to the NCI, so wait before taking more and start with a low dose.
For adults 21+ in legal states. General information, not medical advice.
