Education
Information gaps should be assessed, and, if needed, education should be  offered to people with opioid use disorder on how to reduce the risk of the  following:
    - Acquiring HIV, hepatitis B, hepatitis C, and other  pathogens
- Drug poisoning
- Soft-tissue injuries
- Other harms associated with drug consumption 
Safe supplies
Safe supplies should be offered for the use of opioids and other  substances, including the following: glass  stems, screens, mouthpieces, push sticks, foil, meth pipes, needles and  syringes, cookers, filters, ascorbic acid, sterile water, alcohol swabs,  tourniquets, safe disposal containers, and condoms. 
Infectious disease  testing 
The need for testing for infections should be assessed and, when  appropriate, should be offered for HIV, hepatitis B, hepatitis C, sexually  transmitted infections, and tuberculosis. 
Vaccinations 
The need for vaccinations should be assessed, and, when appropriate,  vaccinations should be offered. Vaccinations to consider include those for  diphtheria, hepatitis A, hepatitis B, influenza, pneumococcal pneumonia, and  tetanus. 
Appropriate referrals 
Assess people for the need for referrals for human immunodeficiency  virus (HIV) and hepatitis C treatment, other substance use concerns, and  housing services. 
Supervised  consumption services
Supervised consumption services are spaces designated exempt from the Controlled  Drugs and Substances Act. In these spaces, people can consume illicit drugs in  a safe, supportive, hygienic environment under the supervision of staff who can  intervene in the event of an overdose or other adverse event. Staff can also offer  assessment and education and encourage engagement with or provide referrals to  other health or treatment services.
