It also limits a person's ability to breathe deeply to provide good support for speaking. Worse yet, smoking is the leading cause of laryngeal cancer. Smoking marijuana may be even more devasting to the voice - as much as 20 times worse than cigarettes. Over-tensing of these muscles can impact your voice. Try gently stretching shoulder and neck muscles periodically throughout the day.
