Adam Carolla’s career changed for the better when he left behind morning radio to join Dr. Drew Pinsky on “Loveline” in 1995. That relationship lasted for 10 years, as Carolla and Dr. Drew dispensed advice on the radio — and eventually on MTV — to the confused and unlucky. After Carolla left the show in 2005, he built his own cottage industry, including books, his Mangria wine label, and a new movie, “Road Hard,” that he recently crowd-funded. At the center of Carolla’s enterprise is Carolla Digital, a podcast network that includes shows hosted by Larry Miller and Penn Jillette, in addition to four that Carolla does himself. One of those is “The Adam & Dr. Drew Show,” which reunites Carolla with his old “Loveline” partner. Carolla and Dr. Drew bring their tour to the Wilbur Theatre Saturday, sandwiched by weekend appearances in New Hampshire and Rhode Island.
