"All persons have the right to equality and freedom from discrimination. This means that all are equal before the law and are entitled to equal protection and benefit of the law, including the enjoyment of all human rights without discrimination on a range of grounds (such as health status, which includes drug dependence).

"In accordance with this right, States shall:
"i. Take all appropriate measures to prevent, identify, and remedy unjust discrimination in drug laws, policies, and practices on any prohibited grounds, including drug dependence.
"ii. Provide equal and effective protection against such discrimination, ensuring that particularly marginalised or vulnerable groups can effectively exercise and realise their human rights.

"To facilitate the above, States should:
"iii. Monitor the impact of drug laws, policies, and practices on various communities – including on the basis of race, ethnicity, sexual orientation, gender identity, economic status, and involvement in sex work – and collect disaggregated data for this purpose."
