The different effects of weed and hash
The question, "What are the different effects from ingesting hash as opposed to herb?" is not one that is as simply answered as one might initially expect.
Hash is made in a variety of ways, and primarily from the two dominant strains of herb: Sativa and Indica, which produce two different effects. Furthermore, hashish can be made from the flowers of any of the hybrid varieties produced by Sativa, Indica, and Ruderalis … and there are a plethora of hybrid varieties, each with their own characteristics and "personalities."
Additionally, some producers of hash incorporate other elements into the mix. These other elements could be opium, herbs, or unknown fillers. All of these variables will have an effect on one's experience.
Most simply put, ingesting hash will produce a substantially more potent effect than smoking the source flower that it is produced from because it is composed of the trichomes of the flowers or buds of the mature female plant. The trichomes are the resinous tiny hair-like follicles that contain most of the bud's THC. Thus, hashish is about as pure a concentration of THC as one can find with at least 40% THC compared to the variants of 10% to about 20% THC potency of the bud.
The high that is experienced from hashish is known to be more mentally fine and clear, and depending upon how much is ingested, definitely more intense. It is easy to find oneself laid back on the couch encompassed in a world of thoughts and dreams, but it doesn't have to be that way if one consumes only a small amount. Small amounts of hash will intensify one's visual and audio perception along with a brightening of the attitude that can come from appreciating the beauty that one perceives while remaining creatively mobile.
Sativa Hashish vs Indica Hashish
Hashish produced from the pure Sativa plant will have a lighter, more mental effect, as that is the inherent personality of Sativa. Sativa is known as the creative and inspirational herb, so the hash experience will embody these qualities. Pure Indica hash will have a more "stony" effect on the mind and body, as Indica herb is also known to produce.
Variety of Hash Production Methods
Many connoisseurs of hashish prefer to produce their hash by simply clipping the trichomes from the bud, compress (or not), and smoke. Other methods of production can be as simple as mixing the trichomes with butter, olive oil, or honey; or as complicated as extracting the resins with alcohols, butane, or simple water.
The final product of hash is estimated to be the mass equivalent of 20% of the herbal bud, thus, one ounce of bud will be reduced to 20% of its original mass, yet maintain the same potency concentration of THC as the original ounce.
Hash extracts composed of trichomes infused with brandy, rum, and other flavorful alcohols are enjoyed by some connoisseurs, administered by drops under the tongue, though isopropyl alcohol is a common (and less healthy) method of extraction. The hash produced by each method provides distinctly different experiences for the user.
