What grounds of appeal have been appealed against the sentence of a convicted drug dealer convicted of possession of a drug with intent to commit a sexual assault?

Defendant's appointed counsel filed a brief pursuant to People v. Wende (1979) 25 Cal.3d 436 (Wende), raising no issues. On December 15, 2015, we gave notice to defendant that his counsel had failed to find any arguable issues and that defendant had 30 days within which to submit by brief or letter any grounds of appeal, contentions, or arguments he wished this court to consider. Defendant submitted a 16-page letter brief, in which he argues, as best we can determine, that: (1) his participation in the crime was "the product of false inducement and entrapment by law enforcement"; (2) the trial court should have instructed the jury on aiding and abetting, and possession; and (3) the court erred in sentencing defendant in light of his "extensive mental health history."
