bk-MDEA (Ethylone)

Bk-MDEAbk-MDEA is currently Unscheduled in the United States. It is a gray area in the law because it may be illegal under the Federal Analog Act.

Addictive Potential: Unknown

Emergency Room Visits Yearly: Unknown

Mandatory Minimum Sentence: Unknown

Mechanism of Action: Non-selective SERT, NET, and DAT inhibitor; 5-HT releaser


bk-MDEA is also referred to as ethylone, 2-ethylamino-1-(3,4-methylenedioxyphenyl)propan-1-one, and bk-3,4-methylenedioxyethylamphetamine. It is a synthetic cathinone with empathogenic effects that are reported to be milder than those of MDMA (Erowid, 2012). Pharmacologically, bk-MDEA acts as a nonselective monoamine uptake inhibitor similar to cocaine, and it also induces the release of serotonin like MDMA. Simmler et al. (2013) noted that bk-MDEA “may be associated with an increased risk of addiction compared to its non-beta-keto analogue [MDEA] because of the stronger relative activation of the dopamine system.”

Side Effects & Adverse Reactions:

bk-MDEA is a research chemical, and little is known about its side effects, adverse reactions, long term damage, and/or addiction potential. Remember, research chemicals are experimental chemicals that are not approved for human consumption. This is because not enough data exists currently about their effects in humans. Although some people are willing to ingest the drug bk-MDEA, it is unreasonable to assume that it is in any way safe to use recreationally.
