The information pertaining to social risks associated with mephedrone is very limited. Whilst there is some limited evidence to suggest greater use of mephedrone compared to other stimulant drugs amongst students of school and college/university age, there have been no studies to determine the impact of mephedrone use on educational outcomes such as attendance, concentration and exam performance. Similarly, there is no data on the effect of mephedrone use on performance/attendance at work, career progression, effects on personal relationships or neglect of family.

There are some healthcare costs associated with cases of acute mephedrone toxicity presenting to hospitals. Most of these involve short assessments within the emergency department; however there are a minority that require critical care admission with greater associated costs. There is also evidence that users are switching from other controlled stimulant drugs to mephedrone. However, it is not possible at this time to estimate whether mephedrone is associated with greater healthcare costs than other stimulant drugs.

There is no evidence related to levels of acquisitive crime resulting from mephedrone use. There have been media and anecdotal reports of some crime and violence reportedly related to mephedrone; however the veracity of these reports is unclear.

There are both media and anecdotal reports of links between mephedrone and violence in Northern Ireland where sellers of the drug appear to have become caught up with the paramilitary activism and informal social control of the drug market. Reports suggest punishment beatings/shootings have been on the increase recently regarding the sale and use of mephedrone. A study with school children reported that mephedrone was more easily accessible than cannabis.
