"I want to thank everyone who has supported me throughout this difficult period," Evans, the former world number 41, said in a statement.
"I have learned a lot about myself in my time away from the game, a sport that I love very dearly. I am now committed to training hard, resuming my career and getting back to where I was, although appreciate this will take time."
Evans was handed a wildcard by the LTA after he passed the "agreed checks" over the last six weeks.
"(Dan) has begun to support the development of the LTA's anti-doping education materials to help emerging young players avoid similar mistakes," LTA performance director Simon Timson said.
