I've had a long history of opiate and benzodiazepine addiction, so my answer is probably going to be quite frank. Short-term: yes. Absolutely. Long-term: nope.
I was more of a casual opiate user than anything. My main problem were benzodiazepines. I'm an anxious person; I am a terrible sleeper. With a bit of internet research, bam: benzos seemed like the perfect drug for me. I could pop a short-acting benzodiazepine before I go to bed, and I'd sleep like a baby. Wake up fresh the next morning with some leftover anxiolytic effect and get on with my life. Then I started to see the other benefit of benzodiazepines - they relieve anxiety. I started to use them before going out, because I'm not brilliant at talking to new people. I used to use them before university presentations. Sometimes I'd use them when I was bored and home alone, so I could pop a film in and get cozy under the covers of my bed, and fall asleep after.
My descent into benzodiazepine addiction wasn't a slow one. Similarly to opiates, tolerance to benzodiazepines builds very quickly. Soon I wasn't just popping 1 clonazepam pill. I was popping 2. Then 3. At my worst, I could pop about 6-7 pills and still feel slightly wobbly but not enough to conk me out. I started to take them more frequently. Bearing in mind they still worked like a charm as long as I dosed it right, but I'd gone from a casual benzo user (once a weekend) to every other day, to every single day.
I realised this pretty quickly, and decided that I needed to stop. I didn't really seek any counselling - I just stopped taking the benzos cold turkey. For 4 days I didn't sleep. I had shivers, "electric zaps" in my brain (that's how it felt). I was at my parents' house for this period of time, and my mum thought I'd come down with the flu or something. I looked pretty ill. Worse was the rebound anxiety at the loss of the drug: after becoming so accustomed to taking it everyday, and feeling on top of the world, NOT taking the drug made me feel awful. I felt even worse than I initially did.
The thing about mental health is that drugs never really "make the problems go away". Our brain's made of networks of neurons, firing neurotransmitters around. Every neurological drug interferes with these chemical pathways in our brain. Mental health issues are not a rash, or a cold, or a sore throat -- things that will "go away" in time, or with a bit of cream or some paracetamol. Mental health issues are rooted deep in our brain.
Sites like "FRANK" are good. But sometimes I think they are a bit too heavy on the "scare tactics" front. I'm just trying to be honest. Benzodiazepines are prescribed because medically, they are very useful for short-term use of relieving anxiety attacks. But not once in a consultation would a GP simply say "take these drugs and you'll be fine". There's a whole host of other options - adjuvant therapies - such as CBT, exercise, counselling - that should be considered, to aid in helping the problems go away. Drugs themselves are not inherently bad; they are, inherently, chemicals. It is the way one utilises such chemicals that becomes harmful. Dependence and addiction are the real problems - and you may find that in depending on drugs, you are creating a whole host of new problems on top of pre-existing ones.
