Tolerance is one aspect of physical dependence. It's basically when your body gets used to a medication and you no longer get the same amount of pain relief from a given dose of the medication. A person needs to continue to increase the dose of the medication in order to get the same effect.
Withdrawal is another component of physical dependence. That's when the medication is stopped abruptly or the dose is lowered too quickly and a person experiences unpleasant symptoms
Vietnam was the first Asian state and the second in the world to ratify the United Nations Convention on the Rights of the Child in 1990. In addition, the Law on child protection, care and education was ratified by the National Assembly in 1991; this Law was then amended in 2004. Since then, Vietnam has issued 22 laws and legislative documents regarding the rights of children. The Prime Minister approved two important national programs in 2011, including the National Program on Child Protection and the National Plan of Actions for Children. I hope this helps!!
