International research has revealed that the more cannabis you smoke, the more likely you are to be lower paid and have relationship difficulties.

The study followed children from birth up to the age of 38 and found people who smoked cannabis four or more days a week over many years ended up in a lower social class than their parents.

It also found that regular and persistent users ended up with lower-paying, less skilled and less prestigious jobs than those who were not regular cannabis smokers.

Financial, work-related and relationship difficulties were further experienced by those taking the drug, which worsened as the number of years of regular cannabis use progressed.
