Primary effects
- Mephedrone acts as a euphoric stimulant with empathogenic qualities, providing high mood and uplift.
- It causes physical sensations like increased body temperature, warmness (with cool, clammy hands), and pupil dilation.
- The substance enhances drive and can lead to a 'rush' of euphoria after insufflation.
Peak character
- The peak is characterized by a happy, stimulated, and euphoric state with an empathogenic edge, described as smooth and not overly physical.
- It puts users in a contented and comfortable 'bubble', making it suitable for socializing.
- Insufflation can intensify the high, making it more heady and closer to MDMA in feel, with a strong euphoric rush.
Negatives / side effects
- Mephedrone can significantly increase blood pressure and heart rate, which is a concern.
- There's a strong urge to redose, especially when insufflating, due to its short duration and rewarding rush, increasing the risk of compulsive consumption.
- Jaw tension and the urge to grind teeth can occur at higher intensities.
Aftereffects / comedown
- The effects wind down gently, with residual stimulation fading into weariness.
- The substance has a short duration with no noticeable hangover or ill effects on the day after.
- The urge to redose dissipates as the effects wear off, returning to baseline without significant comedown.
