The rights-based moral theory is a sort of ethical theory in which the language of rights serves as the core vocabulary for ethical and political philosophy; it holds that a democratic society must protect people while also allowing everyone to achieve personal interests.
Drugs or Substance Abuse can not be justified using the Right Based Moral Theory because, as far as rights are concerned, they are also subject to duties.
One of such duties is:
Duty of Care: Duty of care depicts a circumstance in which you have a responsibility to ensure the health, safety, and well-being of others, which might involve concerns such as ensuring safe working conditions and providing constructive comments.
When a person is under undue influence as a result of drug abuse, they cannot claim to be within their right because they are no longer under self-control but the control of drugs which impair judgement and constitute hazard to others.
