smok has made quite a few pen style mods it'll be hard for anyone to help you if we don't know what model it is.
But, as many have said vape devices don't just decide to go boom on their own.
Think of them as any other electronic device. They only do what they are told. It is up to you, the user to learn about it and use it responsibily.
Now, assuming you didn't buy a smok mech mod and you picked up one of their Regulated pen mods, you should be perfectly safe. Provided you charge it correctly and use the proper coils or build within spec. The bad press you see is predominantly from people using batteries unsafely and quite frankly were ignorant.
