The number of Open Access drug & alcohol journals is growing but their contents represent only a fraction of the research that is freely available through more broadly based medical, health sciences, and social sciences journals.  pen access journal articles are essentially peer-reviewed and available for access through the directory of Open Access journals. PrimeOA Publications International supports this system and provides access to 700+ peer-reviewed journals with no restrictions and thus promotes the Open Access movement with a view to promote scientific advancement. The research articles published in PrimeOA Publications journals are immediately and permanently available online without charge.
