THC Content of Cannabis Products.
Cannabis products include marijuana, hashish, and hashish oil. THC (Tetrahydrocannabinol) gets a user high; a larger THC content will produce a stronger high. Without THC you don't get high.
THC is the primary cannabinoid that produces intoxication when a person uses a cannabis product such as hashish oil (hash oil), hashish (hash), or marijuana.
Hashish Oil: The THC content of good to excellent hashish oil varies from 30% to 80% THC. Reports of white oil (the most potent grade of hashish oil) with a 90% THC content have been reported.
Hashish: The THC content of good to excellent hashish varies from 20% to 60% THC. Reports of hashish with a 70% THC content have been reported.
The THC content of both high quality hash and hash oil has stayed the same over time, with the exception of some exceptional hashish presently produced in Holland.
Top quality hashish produced in Holland (nether-dope) can have a THC content of over 60%. It is more potent than other types of hashish. Only top grades of fresh hash from places like Nepal and Afghanistan can come close.
However, the hashish and hash oil available (in most countries that have to import) has deteriorated in quality since the 1970's. Countries that produce hashish and hash oil have been exporting greater quantities of a lower quality product.
You will probably never encounter very good to excellent hashish or hash oil unless you:
1) produce it yourself
2) know somebody who imports or manufactures it
3) live in (or visit) a country where it is produced
Marijuana has increased in potency since becoming very popular in the 1960's. The increase in potency is due to advanced growing techniques including hydroponics and new high potency seed strains.
Sinsemilla marijuana is a name for female plants that have not produced seeds. Not producing seeds allows the plant to use more energy producing THC and other chemicals that users enjoy.
An ancient tradition for cannabis growers, sinsemilla is the result of removing male plants from the grow environment before they have a chance to fertilize the females.
People who grow hydroponic marijuana indoors always grow sinsemilla. Growing sinsemilla outdoors is harder. A single male plant can fertilize females within an area of a few hundred feet.
In the 1960's and prior to that, the good commercial grade marijuana available to most smokers had a THC content of about 2% to 5% and premium sinsemilla had a THC content that was somewhat higher. Some sources say that marijuana with THC content of 1% to 4% was considered good dope by most Americans in the 1960's.
In the year 2007, the good commercial grade marijuana available to most users had a THC content of about 5% to 10% and premium sinsemilla was about 10% to 20% THC.
Some reports have marijuana with a THC content of over 25% being produced by some advanced hydroponics growers. 25%-30% THC is probably the maximum potential for marijuana. Any claims of marijuana with THC content anywhere over 30% should be treated with skepticism.
