3-CMC - 4-CMC

The effect is described as similar to 3-MMC, but milder. Furthermore, 3-CMC and 4-CMC have a stimulating, uplifting, anxiolytic, disinhibiting, slightly euphoric, concentration- and performance-enhancing and libido-increasing effect. An increased urge to talk and a pronounced empathy have also been reported (although to a lesser extent than with MDMA).

• Avoid the consumption of 3-CMC, 4-CMC and other serotonin-releasing substances such as MAOIs, MDMA, 4-FA, methamphetamine, methylone, 5-HTP and SSRIs/SNRIs. This can lead to a life-threatening serotonin syndrome!
• Mixed use with 25x-NBOMe and 25x-NBOH can lead to excessive stimulation with panic attacks, seizures, mind spinning, increased blood pressure, vasoconstriction, and in severe cases can lead to heart failure.
• Do not take tramadol if you use stimulants. Tramadol and stimulants can both cause strokes, which cumulates the risk.
• Other potentially harmful combinations cannot be ruled out, as there is no scientifically sound information on interactions with cathinones.

• There is little knowledge about Cathinone. Therefore, when you use it, you are exposing yourself to unknown risks. Have the substance analyzed in a drug checking. If this is not possible and you still want to use it, try to reach the desired dose by using small amounts.
• If you decide to use, be as informed as possible about the specific substance and the appropriate dosage - pay attention to your basic mood and the environment in which you use (set and setting), even with NPS.
• Do not buy a product with a fancy name without declaring the ingredient. Legal does not mean harmless.
• Inform your friends about what and how much you have consumed.
• Drink enough non-alcoholic beverages and get some fresh air in between.
• Accept when the effect runs out, don't add to it right away.
• Refrain from mixed consumption, as interactions are dangerous and unexplored.
• Take regular breaks from consumption.
• People with high blood pressure, heart problems, hyperthyroidism, liver and kidney disease, or circulatory problems should not take New Psychoactive Substances.

Since 2023, cathinones such as 3-CMC and 4-CMC have become more popular again and are increasingly being accepted in drug checking offers in Switzerland. The analysis results show that up to 75% of these samples contained synthesis by-products or (additional) ingredients other than the expected active ingredient. If you decide to use it, it is therefore important to have the substance tested first in a drug checking service and/or to test a small amount first.
