Filmmaker Mahesh Bhatt says actor Sanjay Dutt had a really hard time dealing with his addiction to heroin. Sanjay has worked with Vishesh Films, which is co-owned by Mahesh, for films like "Kabzaa", "Sadak" and "Dushman". Last year, Pooja said "Sadak 2", the sequel of her 1991 hit film "Sadak", is in the works.
