  • Addiction. For example, higher doses of opioids can increase the risk of developing a substance use disorder trusted Source in some people.
  • Unintentional medication errors. This may occur from changes to dosing or regimen.
  • Cross-tolerance. For instance, in certain cases, alcohol can cause cross-tolerance to other drugs, like diazepam or valium.
