It is | '''Ethylcathinone''' (also known as '''Ethylpropion''', '''Ethcathinone''', and commonly as '''ETH-CAT''') is a [[psychoactive class::stimulant]] substance of the [[chemical class::cathinone]] chemical class that produces [[stimulating]] and [[focus enhancement|focus enhancing]] effects when [[Routes of administration|administered]]. It is structurally related to [[cathinone]] and [[methcathinone]] (MCAT), which broadly shares the effects profile of [[amphetamine]] or [[methylphenidate]]. | ||
Of the [[substituted cathinones]], ETH-CAT reportedly produces the most moderate and residually long-lasting stimulation, with subtle effects that persist well after the initial rush. It has been described as having a more functional than recreational character due to the limited euphoria it produces for a stimulant, although its short active duration can promote [[compulsive redosing]]. | |||
Very little data exists about the pharmacological properties, metabolism, and toxicity of ETH-CAT, and it has little history of human usage.

Ethylcathinone, or ETH-CAT, is a synthetic [[alkaloid]] of the [[substituted cathinone]] class. Substituted cathinones are all derivatives of [[cathinone]], a stimulant substance which is structurally and functionally related to [[amphetamine]] and the principal active psychoactive component present in the [[khat]] plant (''Catha edulis''). The cathinone molecule is comprised of a [[phenethylamine]] core featuring a phenyl ring bound to an amino (NH<sub>2</sub>) group at the end of an ethyl side-chain that contains ketone group in the beta position. | |||
Ethylcathinone is a | |||
In distinction to its N-methylated lower homolog, methcathinone (M-CAT), ETH-CAT possesses an additional ethyl substitution at R<sub>α</sub>. ETH-CAT can be thought of as the cathinone analog of [[ethylamphetamine]] given it has the same general formula, differing only by the addition of a single double-bonded oxygen (i.e. the ketone group). | |||

Although | Although the effects of ETH-CAT have not been formally studied on the same level as traditional [[amphetamines]] or other substituted cathinones like [[methcathinone]], it is possible to speculate that like other simple [[substituted cathinone]], it most likely acts principally as a [[dopamine]] and [[norepinephrine]] [[reuptake inhibitor]].<ref>{{cite journal | vauthors=((Deventer, K.)), ((Van Eenoo, P.)), ((Baele, G.)), ((Pozo, O.

The result of this is an effective increase in the levels of [[catecholamine]] [[neurotransmitters]] like [[dopamine]] and [[norepinephrine]] in the brain by binding to and partially blocking the transporter proteins that normally clear these neurotransmitters from the synaptic cleft. This enables dopamine and norepinephrine to accumulate between the [[synaptic cleft|synaptic clefts]] of key regions of the brain associated with reward, motivation, satisfaction and pleasure to extra-endogenous levels. This mechanism is thought to account for the [[Stimulation|stimulating]], [[Motivation enhancement|motivation enhancing]] and [[Euphoria|euphoric]] effects that this substance produces. | |||
==Subjective effects== | ==Subjective effects== | ||
At low to moderate doses, ETH-CAT has been reported as being a relatively functional and effective amphetamine-like stimulant for performing general productivity tasks. It has a noticeably short duration of activity combined with a tendency to produce long-lasting residual stimulation well after the main effects have worn off, which can promote patterns of [[compulsive redosing]] in order to maintain a steady level of the desired amount of physical and cognitive [[stimulation]]. | |||
However, at higher doses, it becomes less of a productivity-oriented stimulant and takes on a recreational character, perhaps owing to the inherently distracting nature of the type of [[thought acceleration]] and [[cognitive euphoria]] it can induce. However, even at high doses, it is reported as falling short of many other, far more hedonic and recreational [[substituted cathinones]] such as [[mephedrone]], [[methylone]], and [[methcathinone]] (M-CAT). | |||

The cognitive effects of ETH-CAT can be broken down into several components which intensify proportional to dosage.

{{ | {{Further|Research chemicals#Toxicity and harm potential}} | ||
The toxicity and long-term health effects of recreational | The toxicity and long-term health effects of recreational ETH-CAT use do not seem to have been studied in any scientific context and the [[Toxicity::exact toxic dosage is unknown]]. This is because ETH-CAT has very little history of human usage. Anecdotal reports from people within the community who have tried ETH-CAT suggest that there do not seem to be any negative health effects attributed to simply trying this substance at low to moderate doses by itself and using it sparingly (although nothing can be completely guaranteed). Others have commented that its d-isomer form is virtually similar to the effects of [[amphetamine|d-isomer amphetamine]], and has thus far shown little reason to suspect that its toxicity is radically different (though this has yet to be scientifically validated).{{citation needed}} | ||
It is strongly recommended that one use [[responsible drug use|harm reduction practices]] when using this substance. | |||
===Tolerance and addiction potential=== | ===Tolerance and addiction potential=== | ||
As with other [[stimulants]], ETH-CAT may also possess habit-forming or reinforcing properties. Compared with other stimulants, however, chronic use of ETH-CAT is more likely to be considered to be only [[Addiction potential::mildly addictive with a comparatively low potential for abuse]]. Early studies demonstrate ETH-CAT suppresses cocaine self-administration in rhesus monkeys, without the adverse effects associated with older dopamine [[releasers|releasing agent]] (e.g., amphetamine).{{citation needed}} Despite this, ethcathinone may still be capable of causing psychological dependence among certain users. | |||
Tolerance to many of the effects of ETH-CAT [[Time to full tolerance::develops with prolonged and repeated use]]. This results in users having to administer increasingly large doses to achieve the same effects. After that, it takes about [[Time to half tolerance::2 - 3 days]] for the tolerance to be reduced to half and [[Time to zero tolerance::3-5 days]] to be back at baseline (in the absence of further consumption). ETH-CAT presents cross-tolerance with [[Cross-tolerance::all [[dopamine]]rgic [[stimulant]]s]], meaning that after the consumption of ETH-CAT all [[stimulants]] will have a reduced effect. | |||
