Please do not add promotional material to Wikipedia, as you did to American Academy of Addiction Psychiatry. While objective prose about beliefs, organisations, people, products or services is acceptable, Wikipedia is not intended to be a vehicle for soapboxing, advertising or promotion. Thank you.

Please stop adding inappropriate external links to Wikipedia, as you did with this edit to Opioid antagonist. It is considered spamming and Wikipedia is not a vehicle for advertising or promotion. Because Wikipedia uses nofollow tags, additions of links to Wikipedia will not alter search engine rankings. If you continue spamming, you may be blocked from editing Wikipedia. Thank you.
