Halides

An intermediate in the synthesis of Efavirenz-d4.

4-bromo-2,5-dimethoxyphenethylamine, DOB, its appearance is similar to "Ecstasy". It has a variety of colors (purple, yellow, gray, etc.) and shapes (cow head, butterfly, smiling face, etc.). The chemical structure of 2C-B belongs to phenylethylamine, which is similar to LSD. The efficacy lasts for 3 to 6 hours after taking 2c-b. Its drug power is 10 times higher than MDMA, and the dose to achieve significant efficacy after taking it is much lower than MDMA. The efficacy of 2C-B depends largely on its dosage. Generally, the dosage is 4-30mg. When taking a low dose of 5-10mg, it will produce a hallucinogenic effect. When taking a dose of 10-20mg, the hallucinogenic effect really appears. Taking too high a dose will produce phobic hallucinations, which have the same effect as the reaction after taking sympathetic drugs, such as hypertension, excessive tension and hyperthermia. Although the dependence of 2C-B is very small, drug resistance will also occur if it is taken frequently (more than once a week). For pregnant and lactating women, 2C-B should be taken with caution. After the abuse of 2C-B, the users' visual, auditory, taste and tactile abilities are significantly enhanced, and their sexual desire is hyperactive and hallucinations occur. Excessive use can lead to symptoms such as insanity.

Synthetic cannabinoids have been classified as drugs.
