Cannabis concentrates contain high THC levels that range from 40% to over 90%, [1] [2] stronger in THC content than high-grade marijuana, which normally measures around 20% THC levels. Volatile solvents, such as ethanol , butane , propane or hexane , may be used to prepare extracts, but can and will possibly lead to fire and explosion hazards ...
For example, Δ 9-THC has an EC 50 of 250 nM at CB 1 and 1157 nM at CB 2, whereas PB-22 has an EC 50 of 5.1 nM at CB 1 and 37 nM at CB 2. [8] Adverse effects observed due to synthetic cannabinoid use include acute kidney injury , cardiac toxicity , seizure , stroke , tremor , hypokalemia , and rhabdomyolysis .
Δ-8-tetrahydrocannabinol (delta-8-THC, [a] Δ 8-THC) is a psychoactive cannabinoid found in the cannabis plant. [1] It is an isomer of delta-9-tetrahydrocannabinol (delta-9-THC, Δ 9-THC), the compound commonly known as THC, with which it co-occurs in hemp; natural quantities of ∆ 8-THC found in hemp are low.
The uptempo video from LL Cool J and Eminem, shot in Detroit in late August, recreates a series of classic hip-hop album covers and other imagery.
Ion-exchange resin beads. An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange, that is also known as an ionex. [1] It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.
Instead of smoke, the user inhales vapor. [2] As such, using an e-cigarette is often called "vaping". [3] The atomizer is a heating element that vaporizes a liquid solution called e-liquid [4] that cools into an aerosol of tiny droplets, vapor and air. [5] The vapor mainly comprises propylene glycol and/or glycerin, usually with nicotine and ...
HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE.
