Is it possible to attain wrong mindfulness and wrong concentration? Concentration and mindfulness is a rare achievement. People can have wrong views , wrong intentions but it seems they are able to achieve high concentration and mindfulness.

My question is : Is it possible to achieve wrong mindfulness and wrong concentration?
I think a lot of wrong mindfulness persists today utilised mainly in a non-Buddhist way. Many attempts were made to separate Mindfulness from Buddhist context. Example is mindfulness for mindfulness sake as in therapy; if people don't know the reason are they mindful, then the problem arises. As in, what is there to be found in the present moment, any why? They often don't know the why and what, and this is confusion. 

All of the non-Buddhist approaches as MBSR might go extremely awry. Many charlatans make money by trying to make people to be mindful of the present moment as a "cure-all" therapy for everything. It has caused some cases of depression and people suffering from mental breakdown. Mindfulness like that has long history of creating examples of blind obedience in the East, such as creating Samurai culture in feudal Japan, as means of controlling people without questioning the orders.

In Buddhism however, the reasons are very clear, we want to apply wisdom of the teachings, releasing and transforming karmic seeds, breaking bad habits. It is much safer to do it this way, rather than apply it as a therapy for a specific case. Mindfulness should not be devoid of ethics, for performing good deeds ultimately lead us to a better life. Performing selfless acts destroys clinging and disease of "mine" and therapeutic mindfulness doesn't go that far.

Thus, mindfulness without practising other parts of the path in tandem is wrong mindfulness.

As for Right concentration, there has been a lot of issues recently about mixing Samatha, or mediation in general with psychedelics as it might be profound experience. Many magazines were involved in promoting such ideas. That I would call wrong concentration, the one that goes against composing the mind, but altering it.
